PoS in Ethereum has similar returns on capital as other investments. Currently 2-3% per year. It scales with demand - there is a market mechanism at play.
Claiming that PoS inherently concentrates power in the wealthy misses the point - it mirrors the wider financial market which, yes, benefits the already wealthy.
This is a more fundamental problem that must be solved elsewhere.
And though a single validator is limited to 32 Eth minimum, pooled staking makes these 2%
