It's nice when you are born on second base... Unfortunately, you think it means you hit a double.
I have a friend who lived off of pell grants and loans to make it through a degree. He did not have the aptitude for math or science, and came from a very poor family (his father, at 80, still works at a Burger King.) He did not have connections from his family. He did not have any of the life lessons on how to survive in a middle class system.
He ended up graduating, and could not find a job of any sort. It's quite possible, had he grown up white, straight, and middle class, that he would have been fine.
He tried to go back to school, thinking that this would be the answer. (After all, it delayed loan payback.) In the meantime, he did what he was able to do: sell drugs. He went to graduate school and sold drugs because he couldn't gather the money to move, he couldn't get a job, and he didn't have options that we with privilege do.
It's fun to laugh at the whiny white kids who rack up college credit cards and have to stay at home, but personal responsibility only goes so far.
(PS -- my friend now has a drug conviction, a risk he ran because of one of the choices he made to survive. He now has even fewer choices.)
