How many people don't go to college after high school?

The Department of Education says that 73% of high school graduates do not graduate from college.

Quite alot of people don't go to college because they can't afford it, they have a good paying job already, their grades aren't good, aren't sure what they want to be when they grow up, or their parents didn't do well in college so the teenager believes that he/she won't do well either. Some teenagers also fear of moving out of the house and away from parents.
