Is natural selection legit?

Darwin was a very rich man. He had loads of money. He invested in railroad companies right before their peak and made a fortune. Couldn’t his theory of natural selection be a view relating to the political and economic aspects? He was rich, the main reason was because he knew when to invest and he was good with money. Couldn’t his ideas of natural selection be what we know call social darwinism? His theory of “Nature—love it or leave it” resembles the saying “you can’t fight city hall”. Maybe he was just supporting the legitimacy of his wealth in a very class-struggling time using nature, something that always exists, no matter how much you change it.

Like if I said the reason why I am rich is because I adapted to the economic times, and you did not. This relates to natural selection. I was smart about my money in economic times, and survived, and you were dumb about your money and died out.

Maybe Darwin was just a die hard capitalist rich guy, who wanted to legitimize his wealth in a time where communist revolutions, workers strikes and peasant revolts were going on (the 1800s).

This is mainly from the book in my previous post entitled Biology As Ideology: The Doctrine Of DNA.. I posted an example from the book in case some people did not read it.
