A college degree is useless. And, like you, i have seen many people NOT hire graduates.
It wasn't always this way. Back when unis had to compete on price and quality they strived to have the best and most useful programs. Then the government got involved and made it accessible to everyone even though it already was, just not the elite schools. Now people are taking out hundreds of thousands of dollars in debt that the lenders are very excited about giving them where in the past a poorer person would have to go to a lessor known university and probably still live with their parents while they did so. Nowadays the kids leave the roost as fast as they can, rack up a ton of debt, and end up boomeranging back into their parents' basement anyway.
