We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
However, the reason that is, despite all of the studies showing that most kids benefit little or nothing from college, is because work aptitude tests are now mostly illegal: Thank SCOTUS for Credential Inflation
Sadly this direction has produced a greater obstacle for low income people. Besides the cost of college itself, not everyone (especially people from low income families) can afford 4-5 additional non-productive years after high school
For what its worth, many of our community colleges would be the envy of most other countries. (sometimes even the professors are sidelining from better unis). They are also really cheap.
The biggest draw-backs are thus:
1) No 4 year degree (yet)
2) Although most 4 year schools provide transfer guides so there is no over-lap, a student really needs to know what he's doing to get this right.
3) Many of your fellow students won't belong there and may be a bad influence.
4) Circumstances. Nearly all I have know who've gone to community college have needed to work at the same time. This is hard and most have a hard time doing it in a timely manner.
Even then, they are a treasure (AND, an indicator of how cheap college should/could be). There are other benefits from research universities and a better student body; but, I argue, the alternative is pretty good.
