People that go to college are in average brighter, harder working, more ambitious and for more affluante families and they are meant to make more money (as a group) than people that don't go to college
If you factor in the cost of going to college will you really make more money because of the diploma you will get?

I think that's not really how the world works now. Even those who only finished high school, even elementary, can earn tons of money. It just depend on one's will, hard work and constancy.
