I am going to challenge you to find a single peer reviewed study that concludes what you just said. Almost all recent claims about how paying less is somehow better come from some random HR person's anecdotes. Studies either do not exist or are flawed in some obviuos way.
I respect your argument about how what you said is different from the example I gave. I am not going to comment on this person or the lectures. I am skeptical about any "cool" theory that can't be traced back to a peer reviewed study. People need to realize that really knowing something is very hard. Extraordinary claims require extraordinary evidence.
I am sorry but I can't find a study that concludes "humans prefer pay for work over the same pay for no work". You are just trying to overwhelm me to go and read a vast library of articles.
I found a few studies where the "work" was lever-pushing and the study was with children where as they age they are less and less stupid exactly as expected (by me) http://www.amsciepub.com/doi/abs/10.2466/pr0.1981.49.3.859?j...
So please try to refer me to a study that I can apply in a general office environment with people aged 30 and a real-world job so we can check the claim.
Also there is lots of room between an "adequate" engineering salary and minimum or no wage...
Figuring out how to get underachieving academics into paying or even wellpaying jobs should be a higher priority in politics.
