I question this "license to party" concept.
They work hard, maybe. Some do, some don't. The degrees they get do not guarantee them a job.
Most college students will soon return home to their parents house, and end up over-qualified in some boring, going-nowhere service economy position with huge debts to repay.
The college "friendships to last a lifetime" quickly fade; after all, what are they based on?
Colleges literally see themselves as corporations: they are merely selling a product (in this case, the college experience) for money.
Are students drinking to celebrate their "glory days," or because they are so depressed that they are basically just wasting time & money that could be better invested starting a life?
Because the students don't have much in common, drinking becomes esp. dangerous. After all, the other students are not true devoted friends, or future spouses.
These crimes occur because people tend to see college as what they think that it is supposed to be, rather than looking at the situation in a more detached and unsentimental way.
