We have too much income and social stratification in this country. It's starting to become unreasonable and lead to unexpected adults, including the impoverishment of social life. We have a society based on climbing and positioning and maintaining ground, and that causes a lot of these problems. People don't realize that when they live in gated communities, they've essentially taken up a mentality that confines them to isolation, because once you start to conclude that most people are undesirable and need to kept away, you become cynical and just starting rejecting people for ludicrous reasons, until you end up alone because no one (not even you, if you evaluated yourself honestly) can meet your high standards.
Socially, college was better because a 3.2 English major and a 3.9 math major could eat at the same table and attend the same activities. I didn't even know most of my friends' GPAs. It didn't matter. That enabled a certain diversity of thought that doesn't exist in the adult world.
