There is a part of me that would honestly prefer that everyone went through community college rather than bothering with freshman/sophomore "finding yourself" shenanigans. But I'm biased, since that's what I did... and I'm also biased a second time, because I never had the "must pick a major" uncertainty.
But I think we'd lose a lot of the benefit of doing so if it became a standard.
In addition to teachers focused on teaching, community colleges also have a significant share of adult education... and it's not quarantined away as it is in universities, because the percentage is in the double digits, rather than measured in decimal points.
There are other things, but I'm having trouble capturing them.
When I was in college, I found the evening classes were older people who really wanted to be there and learn. I ended up always selecting evening. At community college especially. There was nearly always 15% of the class that was professionals continuing their education.
Oh, for sure. There was a guy in my Recent American History class who'd been a member of SNCC. Wonderful experience. Still, I think "everyone is there to learn" makes the biggest difference.
