In feudalism, you know full well you're being exploited. In capitalism, you might not be aware of it, but you still are. The idea is that you're being paid for your work but, if the pay is so little that it might as well not matter to the payer at all, and is hardly a living wage, then we're essentially back at square one.

Granted, I don't think we're as close to the grain of outright slavery that feudalism was, but on a long enough timeline, we will be. Companies will want more and more profit, taking more and more from the consumers and working class. People will either fight back or... put up with it.

Please don't be willfully obtuse. You know...
