That's why being a validator requires an amount that can't be achieved by most. It's for those people who really cares about the network and wants to help and with the possible little to no feedback from doing so.
Well, we're entitled to what we want to do with our money and it's up to you if you're going to be one or invest it elsewhere which make it profitable and you will be satisfied with.
It's not really about the money. It's about full decentralization and security of a network.
Would you accept it if your leaders/politicians ask you to pay certain amount of money in order to take part in governance or voting in election?
A public network ought to be open to governance and consensus without restrictions. It shouldn't be determined by money... the qualifications should be by merit.
I think there are networks where you can stake some of amount of money to earn reward without participating in consensus, right? I don't have problems with them even though I have never attempted staking before nor inquire about how they work.
Why I'm more interested in PoS is because of its vulnerablity that can be exploited by those who wish to centralized a cryptocurrency.
