In my opinion, racism (to name one of MANY problems with societies as a whole) could easily be eliminated (as far as humanly possible) through education.
Low levels of education = More competition to survive = Finding a scapegoat for your circumstances
If we could only realize the importance of education and pump a shatload more money into school systems across the nation we'd be much better off, but oh well, thank god for bureaucracy
Ignorance is the enemy, not individual people!
