I do need an income too. I do pay rent, every single month. I do pay a loan, every single month. Bills? You guessed it: every single month. What's your point, really?

People are going to take their pay and do their job because to do otherwise could mean they can't maintain their lifestyle or keep their family provided to the same standard they're currently living at.

Altruism is not a default position, and is unusual in the real world.

I'm not saying that's how it should be, or that people shouldn't work to make it otherwise. But you say why don't all those people walk away from that? How far would you go? What if you had children depending on you? It's very easy to condemn other people as "greedy" but you show a lack of understanding, of empathy, perhaps, for how people in general function in the world if you assume they should just do what you say because "obviously, my moral stance trumps their concerns."

The good thing is that there are multiple sources of getting money.
