College Degree is Very or Somewhat Important...and that trend has been increasing for the "Somewhat Important" group. Using Critical Thinking skills, you'd know that somewhere in the range of 35-38% of Americans Don't have a college degree and quite probably don't have the wherewithal to afford such a career advancing degree, thus losing interest. That's a shame which I believe has been brought on by increasing Wealth Inequality...but that's for another day/thread.
Expanding further, the rapid advancement of AI is going to put stress on those who want to use their minds more than their hands...so that could color the situation on future studies...just saying.
College isn't for Everyone...and it needs to be communicated throughout our educational system that success can be realized, even financially, with a Trade career. A classmate of mine in H.S. went into the Plumbing business and before too long had a summer home on Nantucket Island.
