As others have said, a big part of the problem is the need to eat.

I have a family. I work for a company that does stuff for the government.

I'd _rather_ be building and working on my cycling training app all day every day, but that doesn't make me any money, and probably never will.

All the majority of us can hope for is to build something that helps people and society, and hope that does enough good to counteract the morally grey in this world.

Nothing is ever black and white.
