Community College vs Four Year College

I've been taking some classes at the local community college, kinda treading water, and I've noticed some significant differences between the community college and the "traditional" college.

For instance, in community college, it is assumed that everybody works. Everybody has a job, or at least some way to make money.
At U of A, that was not the norm. Some people had jobs, but it seemed like most did not and that was that. If anything, people got internships over the summer.

In community college, there are security measures everywhere. There are eye-in-the-skys and bubble mirrors and "public safety officers" everywhere. Everywhere you go, you're potentially being watched.
At U of A, there were entire buildings that seemed like they should have cameras that didn't. Of course, the Student Union was supposedly more secure than a Vegas Casino, but labs and performance spaces were left to their own devices. I mean, locks are breakable and lasers are fricken valuable. I guess there was a higher level of trust?

At community college, people are older. There are still the 18-19 year olds, but a lot of the people who are in freshman-level classes are 21+ - and in every class I've been in there is at least one person who is significantly more established than the average college student is expected to be.
At U of A, seeing anyone over 25 who wasn't a professor or TA of some kind was abnormal and viewed with suspicion. You are expected to go in at 18, do your four years, and either do grad studies or get TF out of there. No one old is allowed.

At community college, you tend to fend more for yourself. There's public high school level disparity between advisers and students, and while the professors are nice, they actually go home at the end of the day.
At U of A, you are smothered with people trying to make your life easier. There was always a prescribed path, a group you get railroaded into, someone you gotta meet to finish something out - at least when you're a freshman - then it goes away fast.

SO overall, plusses and minusses both ways. You don't always necessarily get what you pay for.
