You can call that feudalism, among other things.

But that’s because it’s intentionally hard to tell if it’s feudalism in a capitalist hat or capitalism in a feudalism hat. That’s what oligarchy is.

Capitalism in itself is private enterprise, which is where capitalism defenders usually start trumpeting that capitalism isn’t actually evil. I think you can maybe make an argument that totally unregulated capitalism isn’t evil, because it’s basically anarchy. But the reality of human greed hits hard and always leads to self-regulation (collusion) and external regulation (coersion), which muddy the waters and lead to oligarchy and feudalism regardless as politicians and businessmen consolidate power.
