If something is important enough to you that you feel the urge to donate your money or time to it, I think it's best to try to express that form of giving through your career, not just as something you do on the side.

In my opinion your career should be your best outlet for giving.

Understand that relationships are more important than contracts. Business deals are relationships between people.

Do you think you're supposed to ignore it and hide from it and wait for someone else to solve it for you? If you notice it, you own it.
