I too don't think formal upper level education is a tell all to one's intelligence! I know lots of extremely intelligent people who never attended
college. I also know complete idiots who graduated college.
However, those who want careers in specific careers more then likely need to attend college in order to work in that career/field. There are just
some things life cant teach you
I graduated High School, got my AA in Business Administration....got TONS of work experience then decided to go back to school for Criminal
Justice/Forenics. I have maintained a 4.0

and been on the Dean's List (I feel I can brag since its not easy and an accomplishment!!)
