You would prefer college admissions be based on a blind lottery system? That seems like a great way to destroy an education system. Would degrees then be allocated randomly to people who may or may not have studied? Maybe you’re being sarcastic.
That's missing the point. Its the staff/teaching that has become insular. The students enter with lots of creativity and individual ideas. They get graded and norm'd to death, step into line or fail, and spit out.
