This is the student union near me. It takes up a city block.
I went to school here before this was built. We had class 5 days a week. Two days a week you were taught in a lecture hall with hundreds of other students tying to understand math from someone with an accent facing a chalkboard using sidewalk chalk. Three days by a TA who did not care.
Everyone needs to go to college to get a good job we have been taught. It has almost become, everyone who wants more than minimum wage needs to go to college to get a job.
There is nothing you can't learn from books and the Internet that you can't learn in college. Anything is what you make of it.
