Funny to find this top comment, since I just had this exact train of thought an hour ago. It went something like this. It's a common unexamined platitude that it takes a huge amount of work, and especially sacrifice to be able to live well. That might well be true under certain conditions of, say, undeveloped agrarian civilizations. It shouldn't still be true of ours, and yet it is. Our infrastructure and supply chain create so much abundance of every imaginable thing, from necessities, to frivolities, to luxuries. There's no way that it actually requires a huge amount of toil and pious sacrifice for each person to earn their share of this abundance. And yet it does. Every time I try to discern why, it always comes back to the same thing. Everything is owned. On the very large scale, everything is owned by a relatively tiny handful of people. And those people absolutely depend, for their absurdly outsized fortunes, on everybody else working for them. The owners of everything want you to work for them.

It's exactly as you say. It's feudalism. Wealth inequality is feudalism.
