They don't want us to realize that the reason college is so important is because children in the U.S. are deliberately prevented from learning anything valuable in their first 13 years of "education".
My dad had a friend in high school who taught shop class. He helped me about 6 years ago with his shop tools. He was forcibly retired a few years later because the administrators decided that woodworking and metal working aren't important to people who are going to college, which is all that matters in a globalized society.
Apparently that's the feedback loop: Grade school gets you ready for middle school, middle school for high school, high school for college, college for graduate school, graduate school for unemployment.
According to a book from the 1970's I found at a thrift shop years ago ("The Screwing of the Average Man"), College used to be something that the upper class sent their children to, so they'd have a leg up on the un-credentialed proletariat. After WWII Congress passed the GI Bill to pacify all those ex-soldiers, and college became affordable for everyone. I was going to say that college is a waste of money, but the real waste is in K-12 - at least in College you mostly take only the classes you care about.
