I think PoS is unethical - it rewards whales and makes a coin look like a ponzi scheme
You have a problem with it rewarding people who buy and hold?
If it only rewarded those with deep pockets *cough*next*cough* then I could see your criticism, but that's not the case.
Single coins can stake so anyone can get in and build a stack.
It's not Microsoft stock but a currency. Name 10 currencies in the real world with a proof of stake interest (not from the bank but from new allocation) and get back to me.
