I know dozens of high school drop-out, high school grad, GED and college drop-out millionaires and I’ll bet everyone here does, too. In my experience as a sales recruiter, I’ve found that high school level people often make better salespeople. I don’t know what they’re doing to people in college these days, but it’s sure goofing them up in sales.
Anecdotal information doesn't change the reality that the less education you have, the more difficult it is to find employment and good salaries. Of course it doesn't help to bring in 1.1 million permanent legal immigrants annually along with 650,000 guest workers every year to compete with Americans for jobs.
The top tier of students who only have HS diplomas have much more potential than the bottom tier of those who went to college, delayed growing up for a few more years, got hopelessly in debt, and still haven't developed workplace skills. I look around me, and it seems that the smarter business managers are working with their best HS grad employees so they can move up and feel secure in those work environments.
The answer isn't more college. It's more vocational and business-management learning opportunities in HS.
