It depends on the degree. I'm a Millennial and got my CS degree for $15k, which was a smart investment (and make no mistakes, degrees ARE investments). At the same time I have a friend who is going into a few hundred thousand dollars worth of debt to get a PHD in History. That's not a good investment, when you look at time + money vs return.

"Just get a degree" is bad advice. I know electricians that make more money than me, and work shorter hours. "Get a skill" is good advice, and college is only one way of doing that. But you can't dismiss personal responsibility when it comes to decision making, both good and bad.
