Most people with a university degree don’t have a traditional university education.
I’m very much pro-education, and think that US high school should include the first two years of a current university education (grades should be roughly split between D, C, B and A, where D means “meets curriculum requirements”).
After that, I don’t think many people should go to a university. Instead, the state should provide up to 10 years of vocational education (splittable and redeemable at any point in life) or 8 years of university education (subject to a B or better average in high school).
Most vocational programs would be under 3 years, so you’d get three-four cracks at finding the right profession for you.
University track would be targeted at educators, researchers and entrepreneurs.
I think this would be better for every socioeconomic demographic in the US, and also help alleviate the housing shortage, enable modern manufacturing, fix many current issues with healthcare, and so on.)
