> why aren't more workers "happy capitalists"

Only idiots are always happy. If we see flaws, no matter how small, we try to proceed to the next level by fixing those, there is a brief moment of perceived happiness, but it passes rather quickly, and so cycle continues. What you described is Work-In-Progress. Capitalism is the system that allows that, it allows itself to self-correct.

> Or the people soon displaced by computers and algorithms

Everything that can be automated - should be automated. Humans is a creative reserve that is limited, physical labor needs to become obsolete. Also you don't see any horse carriage operators complaining about being displaced by automotive industry, do you?

> let just not forget that we live in a "society" and not in a box, everyone for themselves

That's right, everyone is not against you, they are just for themselves.
