Yes its possible. I have no intentions of going to college anymore, but am going to go into trade school after the military. I know people who are going to college, or have graduated and have no job that any person who didn't go to college could get.
All college gaurentees are expensive pieces of paper once completed. I looked around my class when the teacher asked who is going to go to college, I see hands going up that shouldn't be. The kids that do are frigging idiots who have no place in high school. They have no grasp on reality, don't do their work, and can barely pass highschool courses. Once they go to college noone will make sure they're homework is complete or try to help them. They'll just mark them absent, forget about it, and the school keeps collecting the nice size checks. A lot of people are going to college b/c its the cool thing to do.
