I don't think this tells the full story.

There are of course examples of individuals who do very well without a post-high-school degree.

A big part of it, in my view, is how driven the person is. Some people are not very driven. If you're not driven enough to go to (and get through) college, you're probably not driven enough to do much more than low-skill, low-paid work. So taking for argument's sake that statistic is true, it doesn't say anything about cause and effect.

If you're driven to succeed, you'll find a route to success, whether it's college, military, vocational/trade school, self-teaching, or other non-traditional paths.
