Credentials to get rich

As I said the other day, I was talking to a guy I knew in high school. He spent as long in college getting his BA that I took to get my Master's degree. I don't really acknowledge my undergrad degree in the sense that it's a gateway degree that allowed me to get to grad school with the least resistance given when I decided that I wanted to pursue a career in librarianship.
Being from a small town, what did I know about what I wanted to be? I'm from a town that lacked any striving industry, and the town was in steep decline. People had jobs, but most of the jobs didn't require any formal education. Sure teachers, doctors, and pharmacists were required to have at least a bachelor's degree, but everything typical had its credential potentially obtained upon completing high school or a 2 year degree from the technical college.
University education was pushed as being to what everyone should aspire, but to what end does a bachelor's degree matter? A job is not guaranteed upon graduation. Not even from a "career college" can such a claim be made, otherwise lawyers would be filing class action suits until all such schools were out of existence.
There are a lot of millionaires that do not have college degrees. A lot didn't inherit their wealth, but rather worked within their profession until they made it to the upper tax bracket.
What do they do? For the most part, they're entertainers or in the entertainment industry, which says a lot about our society, doesn't it?
