I went to school in Boston and knew lots of people of Harvard and MIT, and the amount of cheating was absolutely staggering. The "Greek"/frat network contributes to this cheating culture greatly (some houses more than others, but they're all part of it.) Personally, I think that some of these people are so used to being that #1 student that when they're surrounded by other #1'ers, they do whatever it takes to remain…
This is a _cultural_ difference of MIT; people tend to work with one another, or they tend to fail. They learn it freshman year, and it's ingrained in their psyche from then on.
Interestingly, the line between cooperative work and cheating is difficult to discern and mostly set up by the professor. When the professor does not say one way or another if the work is collaborative, students will generally consider it collaborative.
As for the "[n]ever build cool things" troll, I'll let you google the number of neat inventions by famous MIT / Harvard alums; I won't waste my time.
