College was a fun time and I met a lot of friends, and, 30 years later, I actually stayed in touch with none of them beyond the first 3 or 4 years. It is definitely easier to make friends in that kind of situation, but it doesn't mean they remain long term friends, ime.
I think if anything all the anecdata suggests that the reverse of the OP's claim is true: that college helps foster the understanding that some/most relationships are fleeting and have their beginning and their end.
Feels a lot like the kind of relationships you get into in the business world. I wonder if that's a coincidence or by design.
