As an older millennial, I think if you're under 30 it's too soon to judge how valuable your education is.
College grads almost always make more in the long term. I make pretty decent money now, but when I was in my early 20s just out of college I was only making like $14/hr and I didn't find my "career" job until I was in my late 20s.
\When I was under 25 I'm sure some people in my age group who didn't go to college were making more than me at the time, but now I have an office job with good benefits, ability to work from home and a pension and those same people either aren't making much more than they were back then or are stuck in physical labor jobs that'll probably give them health problems.
