In reality, there is no such thing as perfect distribution model. Same goes in the fiat world. There are bound to be rich and poor people. I know you must be expressing your concern on those who got in early but early bitcoin adopters get the most share and the justification is similar like being the first to invest in IPO. People like you are me who got in later might not accumulate that much but at least we still consider ourselves lucky to get in early and we are able to purchase btc at current price (if you imagine that it might worth 10 times or more in the future).
Exactly. Anytime you attempt to artificially distribute wealth you will only get people who will end up gaming the system and will end up with something that is unfair to most.
The current PoW distribution system is the best, as eventually the difficulty will be directly linked to the cost of electricity and the price of bitcoin, so it will cost roughly the same to mine one bitcoin as the market value of such bitcoin
