Let's say this socialist Utopia happens, it won't but let's say it does. Then someone like Trump gets elected.In theory, nothing much depending on which branches and school of thoughts you look at. However, it has historically been used by tyrants to establish a form of government where the means of production is solely owned by the state and held by oligarchs, forcing the working class to essentially be slaves.
Because these governments like the USSR and China call themselves socialist, the capitalist powers that be use them to fear monger people into submission and make them think that is what socialism solely is, and thus anything that's vaguely socialist or even just good for the poor and downtrodden is seen in a bad light (in the US, at least).
How fucked would we be
