Ask HN: How do you solve social issues easily?

Why is it so difficult to solve social issues?

It seems so much easier to find ways to grow large prize winning watermelons in the middle of the Sahara Desert then it is to get people to actually solve a real social problem.

I've seen hacks (e.g. guilt for donations) to solve problems but these hacks rarely change the way people and most of them don't seem to be very permanent solutions.

Has anyone here thought of any way to solve real social problems easily?
