that is exactly the problem right there. you are comparing two different things that are not even similar.

an altcoin dev who wants to become rich, premines his coin, runs an ICO,... so in an instance (usually without even doing much since they mostly copy code from each other) they gain a lot of coins which worth a lot of money.
now you say Satoshi, he did NOT premine bitcoin, he did NOT run ICO, he did NOT get paid to create bitcoin. what he did was that he (like many others) started mining bitcoin on a level playing field. if he owns 1 million bitcoin he deserves it, many others also own 1 million bitcoin since they mined in early days like Hal Finey for example.
... and that is a huge difference.
