Greedy people are more likely to end up wealthy. Greedy people are also more likely to end up doing ethically dubious things.
Of course, any wealth at all is unethical if you’re being honest with yourself. There’s a famous passage in the Bible.
Jesus was out teaching his disciples or healing people- whatever he did. And a rich man comes up to him and asks
“Jesus, I want to follow you and go to heaven. Please tell me what I should do”
What did Jesus say? Jesus told him to a) sell all of his shit b) give that money to charity c) physically follow me around
What did rich guy do? Have an epiphany about morality and living the good life?
No, he cried. He cried because he didn’t actually want to let go of the good things he had for morality.
All of us in first world nations are guilty of this to some extent. The way our world is shaped you essentially have to be unethical to survive. There are levels to it, of course. But I think your perspective is too black and white and needs a little nuance. Seem like a teenager.
