College is not necessary in life, why most jobs in the world don't require it. I'd say maybe Engineers, Doctors, scientists/researchers, teachers, lawyers (because the law is so vapid there's no other way to understand half of it), and a few other jobs require it, for obvious reasons. However the bulk of jobs and those, but more of grunt work and only really need some good orientation. Sure I plan on going to college, but then again I plan on designing rockets to send you to the Moon, Mars, Titan, etc.
On the other hand there are jobs that college isn't necessary about, in fact maybe even counterproductive. People like internet reviewers don't require that kind of education. My mom for instance makes beads, and where she took a few classes on it, she didn't get a degree on 'glass chemistry' or something.
Unfortunately, where I don't want to admit it unlike the reviewers, and jewelry designers, etc. most jobs are starting to require more degrees (or at least have higher priority) which is a garbage outlook when they may not have even learned anything in college that can be applied to their new job. It also doesn't help that schools are ramming into students heads that you need a college education to succeed in life, when really the most successful people in life only really get there by chance. The idea of the UnCollege movement is one that I can get behind for this particular reason.
