Regarding competitive - ok, but where it isn't?
Competition is primarily about *individual* ambitions and these can be reinforced by the system but are not given exclusively by the system.
In Soviet science there was just as much competition as in the West and the greatest minds (like Sergey Korolyev) were quite a dicks in person. Same in open-source which is quite collaborative by nature but people like Linus Torvalds are both great and dicks at the same time...
