"College for All" is a non-starter, in large part because not everyone is entirely capable of or (more importantly) at all interested in earning a college degree. That said, if "Career Education for All" is on the table, I'm all in (and willing to pay my share if needed). It benefits all of us to have more of our fellow citizens gainfully employed and doing stuff they're good at.

One way to positively influence that outcome might be to assess students midway through high school (as many other countries do), to see what professions/vocations they might thrive in. Send the academically-motivated to college and those who are vocationally-motivated to appropriate trade schools or training programs, all on the public dime. Expensive to the point of being somewhat painful? Very probably. Worth it? Almost certainly, especially when comparing the social benefits on Earth to those achieved by putting billionaires in space.
