[Marvel/DC] With all those heroes that can do impossible, why isn´t either Earth basically a paradise?

I mean, if you have reality warpers , insanely smart people , why no one goes and cure cancer, deal with famine etc.?

In general, the heroes are too busy keeping the world from falling apart from cosmic beings going awry, alien invasions, attempted world conquering events, and sitting down to make a plan to fix the world and make it a paradise just doesn't happen because as soon as they get started, here comes a supervillain team-up.   


Likewise, when an incredibly hero tries to make the world a paradise, they usually go too far and the other heroes end up having to stop them and restore the world back to its original state.
