It's already happening in some places. E.g. here in eastern europe. After USSR fell, everybody wanted to go to university. Because during soviet times you'd get assignment to a cushy job for life. Yet people missed that it's over and just having a degree from random university won't land you a job. Thus we have a shit ton of not-so-talented poorly motivated people with a degree. And a lack of tradesmen. End result is that a professional (show up on time, not drunk, do job up to specs) tradesman easily makes 2x or 3x salary of average citizen with university degree. Let alone it's hard to land a job in one's specialty because the market is overcrowded. Thankfully the trend is slowly reversing. Since the '08 crash tradeschools enroll more and more people. There's still a massive gap to be filled.
