Twenty-first century imperialism has changed its form. In the 19th century and the first half of the 20th century, it was explicitly related to colonial control; in the second half of the 20th century it relied on a combination of geopolitical and economic control deriving also from the clear dominance of the United States as the global hegemon and leader of the capitalist world (dealing with the potential threat from the Communist world). It now relies more and more on an international legal and regulatory architecture—fortified by various multilateral and bilateral agreements—to establish the power of capital over labor. This has involved a "grand bargain," no less potent for being implicit, between different segments of capital. Capitalist firms in the developing world gained some market access (typically intermediated by multinational capital) and, in return, large capital in highly developed countries got much greater protection and monopoly power, through tighter enforcement of intellectual property rights and greater investment protections.
These measures dramatically increased the bargaining power of capital relative to labor, globally and in every country. In the high-income countries, this eliminated the "labor aristocracy" first theorised by the German Marxist theorist Karl Kautsky in the early 20th century. The concept of the labor aristocracy derived from the idea that the developed capitalist countries, or the "core" of global capitalism, could extract superprofits from impoverished workers in the less developed "periphery." These surpluses could be used to reward workers in the core, relative to those in the periphery, and thereby achieve greater social and political stability in the core countries. This enabled northern capitalism to look like a win-win economic system for capital and labor (in the United States, labor relations between the late 1940s and the 1970s, for example, were widely termed a "capital-labor accord"). Today, the increased bargaining power of capital and the elimination of the labor aristocracy has delegitimated the capitalist system in the rich countries of the global North.
Increasing inequality, the decline in workers' incomes, the decline or absence of social protections, the rise of material insecurity, and a growing alienation from government have come to characterise societies in both developed and developing worlds. These sources of grievance have found political expression in a series of unexpected electoral outcomes (including the "Brexit" vote in the UK and the election of Trump in the United States). The decline of the labor aristocracy—really, its near collapse—has massive implications, as it undermines the social contract that made global capitalism so successful in the previous era. It was the very foundation of political stability and social cohesion within advanced capitalist countries, which is now breaking down, and will continue to break down without a drastic restructuring of the social and economic order. The political response to this decline has been expressed primarily in the rise of right-wing, xenophobic, sectarian, and reactionary political tendencies.
The early 21st century has been a weird time for imperialism. On the one hand, the phase of "hyper-imperialism"—with the United States as the sole capitalist superpower, free to use almost the entire world as its happy hunting ground—is over. Instead, the United States looks significantly weaker both economically and politically, and there is less willingness on the part of other countries (including former and current allies, as well as those that may eventually become rival powers) to accept its writ unconditionally. On the other hand, the imperial overreach that was so evident in the Gulf Wars and sundry other interventions, in the Middle East and around the world, continues despite the decreasing returns from such interventions. This continued through the Obama presidency, and it is still an open question whether the Trump presidency will lead to a dramatic reduction of this overreach ("isolationism") or merely a change in its direction.
The latter point is important, because there is little domestic political appetite in the United States for such imperial adventures, due to the high costs in terms of both government spending and the loss of lives of U.S. soldiers. The slogans that recently resonated with the U.S. electorate, such as that of "making America great again" were in that sense somewhat self-contradictory—looking towards an imagined past in which the American Dream could be fulfilled relatively easily (at least for some), without recognising that this was predicated upon the country's global hegemony and far-flung empire. The global context of imperialism is a complex one, in which the contours shift constantly. Recent political changes in various countries of the North have meant that global strategic alliances are also much more fluid than at any time over the past half century. The most talked-about current examples are the changing attitude of the Trump administration towards the United States' traditional enemy, Russia, and the complicated international politics emerging in Europe, with the Brexit vote and the emergence of right-wing political forces in a number of other European countries. But it is also evident in other parts of the world, notably in China, where traditional friends and foes are no longer so easily demarcated. Yet there is another sense in which the fundamentals of the imperialist process have not changed, even as the forms in which they are expressed are altered.
Defining imperialism broadly, as Lenin did—as the complex intermingling of economic and political interests, related to the efforts of large capital to control economic territory—it's clear that imperialism has not really declined at all. Rather, it has changed in form over the past half century, especially when we embrace a more expansive notion of what constitutes "economic territory." Economic territory includes the more obvious forms such as land and natural resources, as well as labor. These are all still hugely contested: The wars for oil in the Middle East, the continuing attempts at land grabs in Africa, and the struggle over the fruits of extraction of natural resources in parts of Latin America and Asia all testify to this.
But the struggle over economic territory also encompasses the search for and effort to control new markets—defined by both physical location and type of economic process. Understanding territory in this way helps us understand how imperialism is still very much alive and kicking, even though some of the more classic features (such as direct colonial control and annexations) are less in evidence.
One of the key aspects of recent capitalist dynamism has been its ability to create new forms of economic territory, bring them within the realm of capitalist economic relations, and therefore also subject them to imperialist control. Two forms of economic territory that are increasingly subject to capitalist organization and imperialist penetration today are 1) basic amenities and social services (earlier seen as the sole preserve of public provision) and 2) the generation and distribution of knowledge. A major feature of our times is the privatization of areas that, until recently, were generally accepted as public responsibilities.

These processes imply worsening material conditions, for most workers, in both the periphery and the core. Imperialism has generally weakened the capacity for autonomous development in the global South, and worsened economic conditions for workers and small producers there, so that is not altogether surprising. The growth of employment and wages in China is as a break from that pattern and an example of some benefits of global integration, at least for a subset of working people in the developing world. The beneficiaries, however, remain a minority of the workers in the global South. In other countries generally seen as "success stories" of globalization, like India, the economic realities for most people are much bleaker.
The more obvious—and potent—change that has resulted from this phase of global imperialism has been the decline of the labor aristocracy in the North. The opening of trade, and with it a global supply of labor, meant that imperialist-country capital was no longer as interested in maintaining a social contract with workers in the "home" country. Instead, it could use its greater bargaining power to push for ever-greater shares of national income everywhere it operated. This was further intensified by the greater power of mobile finance capital, which was also able to increase its share of income as well. In the advanced economies at the core of global capitalism, this process (which began in the United States in the 1990s) was greatly intensified during the global boom of the 2000s, when median workers' wages stagnated and even declined in the global North, even as per capita incomes soared. The increase in incomes, therefore, was captured by stockholders, corporate executives, financial rentiers, etc.
The political fallout of this has now become glaringly evident. Increasing inequality, stagnant real incomes of working people, and the increasing material fragility of daily life have all contributed to a deep dissatisfaction among ordinary people in the rich countries. While even the poor among them are still far better off than the vast majority of people in the developing world, their own perceptions are quite different, and they increasingly see themselves as the victims of globalization. Decades of neoliberal economic policies have hollowed out communities in depressed areas and eliminated any attractive employment opportunities for youth. Ironically, in the United States this favored the political rise of Donald Trump, who is himself emblematic of the plutocracy.
Similar tendencies are also clearly evident in Europe. Rising anti-EU sentiment has been wrongly attributed only to policies allowing in more migrants. The hostile response to immigration is part of a broader dissatisfaction related to the design and operation of the EU. For years now, it has been clear that the EU has failed as an economic project. This stems from the very design of the economic integration—flawed, for example, in the enforcement of monetary integration without banking union or a fiscal federation that would have helped deal with imbalances between EU countries—as well as from the particular neoliberal economic policies that it has forced its members to pursue.

It is sad but not entirely surprising that the globalization of the workforce has not created a greater sense of international solidarity, but rather undermined it. Quite obviously, progressive solutions cannot be found within the existing dominant economic paradigm. But reversions to past ideals of socialism may not be all that effective either. Rather, this new situation requires new and more relevant economic models of socialism to be developed, if they are to capture the popular imagination. Such models must transcend the traditional socialist paradigm's emphasis on centralized government control over an undifferentiated mass of workers. They must incorporate more explicit emphasis on the rights and concerns of women, ethnic minorities, tribal communities, and other marginalised groups, as well as recognition of ecological constraints and the social necessity to respect nature. The fundamental premises of the socialist project, however, remain as valid as ever: The unequal, exploitative and oppressive nature of capitalism; the capacity of human beings to change society and thereby alter their own futures; and the necessity of collective organisation to do so.
