Mining with computers to earn ETH will be obsolete. Your coins can then be locked up in holdings to support the ethereum infrastructure to essentially mine in that fashion instead. You'd get an eth interest rate on your locked up eth over time as your reward. You'll have to have a certain amount of eth to qualify individually to stake or be part of a pool.

the rich get richer

Somewhat. You don't have to be rich to get rich in cryptos. Yes, it takes money to make money, but all you need to do is get in early. How? Study, learn, dig, take smart risks, and WAIT for the investment to mature. $125 in ETH at $12 in January would've given you 10 ETH, likely the minimum to stake. Do that a few times and make your own luck/wealth.
