I'm talking about incentives here, and people do things almost entirely on selfish impulses. Money is a powerful motivator, and people are strongly motivated to not spend their own money on bullshit. That motivation is absent when government funds things - but other motivations remain.
Pulitzer Prizes have been awarded for work later shown to be complete frauds. Those severely damaged the value of getting one. I know I don't attach any respect for Pulitzer Prizes.
