Also it's interesting that for any job that requires advanced problem solving (the jobs that can't easily be automated), monetary rewards, especially predictable ones, cause people to perform worse. Thinking about the money takes away from our brain capacity to solve the problem and for any advanced work people will actually be more productive if you can provide different incentives. For people working at a factory line this is different and monetary incentives have been proven to work but that kind of jobs are on their way out.
The fact that we have cool gadgets like iphone and android phones, or even just PCs and operating systems, which were designed by brilliant people with competitive monetary incentives, kind of goes against that theory.
