On an individual level, you can do something about drug addiction at least. The issue is when the problems are not individual with readily identifiable solutions, but tragedy of the commons sort of situations brought up by many dozens (thousands, millions?) of factors both known and unknown. Even interaction effects between known factors might be little studied.

So really, what is anyone to do? "Vote, donate, protest" hasn't been much of a needle mover in the grand scheme of things compared to profit incentives and the march of capitalism.
