Alright, I'm going to break this down for you since you seem to keep coming close to getting the point before retreating to "COMMUNISM!" Note, I'm not going to advocate for any other system, I'm just pointing out the fundamental concept of capitalism and the great inequality it creates.
Let's just start with the very basic concept that Capitalism is a system based on exploitation. Every single worker is exploited under capitalism. EVERY worker. This is because workers that produce a product do not own a share of the product in proportion to their labor. Rather, the capitalists own both the means of the production and the end product through their ownership of the capital used to create the enterprise. The capitalists reap the majority of the profit and then renumerate the workers an inequal share, typically as small as possible, to keep them able to continue producing said product.
Now, you in the comfortable West will say, "big deal, I already know that. So long as the exploited worker can live comfortably on their wage, it's fine that profits are not shared equal to the labor produced." Yes, this would be the case for a worker such as a Software Engineer working at Google. They help create a product that makes the company billions while they in turn are treated to a six-figure salary which allows them to afford, presumably, a nice house and car. While they are exploited, they are able to live a comfortable life, what's wrong?
Well, my good friend, the exploitation does not stop with the Google Engineer making six figures, the exploitation is GLOBAL. You are not accounting for all aspects of the market which produces the good, because then you will see that the majority of workers exploited are actually NOT living a comfortable life. Because that exploitation extends outside of the West and into the Global South. You see, while EVERY worker is exploited under capitalism, not all workers are exploited equally. You enjoy a cheap cell phone because children in Africa die mining that sweet cobalt needed as a critical component. Workers in S. America and elsewhere develop lifelong health issues mining lithium to power that battery in your laptop. Children in Vietnam help produce those cheap shoes you enjoy wearing. Etc. Etc.
This is not a bug of capitalism. There is no guard rail you can ever put in place to prevent this because the system only works by exploiting the working class and draining resources for profit. The more "guard rails" you put in place in one area, just means greater exploitation of others in another area. You complain about the rising cost of goods, but those costs rise when capitalists are forced to improve conditions of workers; because capitalists will not eat those costs and ensure a smaller profit. They must be passed on to the consumer. As such, capitalists will always look to reduce such costs by finding a new segment of workers to exploit. This is why once worker conditions improved in America, manufacturing very quickly shifted overseas where such protections do not exist and labor costs are cheaper.
