Yeah, but you are assuming people only go to college for its educational value , ignoring that college grads tend to have much higher wages and lower unemployment compared to high school grads. If you look at FIRE subs for example, almost everyone who attains early retirement has a degree. The college wage premium is amplified by both higher wages and higher returns from investments by investing said wages in rapidly appreciating stocks and real estate (the post-2009 bull market in real estate and stocks, on an real basis, exceeds even the '80s and '90s).
