Something dangerous about PoS you need to understand

I mean Proof Stake (PoS) that places huge Stake limit on those who want to become Validators. It will favour the few who have powers over the printing of centralized currencies like fiats. The PoS is like handing community power back to those who controls this opaque and centralized currencies/world. They include those some activists call bankster or something. Such PoS is a kind of takeover mechanism built into lots crypto for the hidden centralized powers(knowingly or unknowingly).
If fiat currencies are not that transparent, then bear in mind that they could be abused and printed limitlessly for the buying up of PoS coins for consensus/governance. And the so called banksters (who most likely know themselves) could become the validators of "Decentralized" Network. They(instead of all community members) will control the Network.
This is crafty way of centralizing and controlling a Network
