Actually government does. It makes sense to nudge people towards acquiring more skills and they routinely do that. Also, the economy is punishing for those who don't have a college degree (it always was, but perhaps not at this level.)

And how did we reach here? Government policies. I am not saying that these policies were bad. But there can be no denying that government is the major reason why more and more people are going to college. And definitely, if college is not free or subsidised, they will be forced to take loans. Again, because economy is punishing for those who don't have a college education.
