I saw the video the other day, and I've read similar research papers by scientists tasked with the goal of "dis-entangling performance from pay". A question to ask is, "Who sponsored these studies and why?" I speculate business leaders do because their goal is to increase profit margins, which return more money to investors and allow them to increase compensation for themselves. That isn't exactly Utopian, but I doubt Utopia seeking individuals sponsored such research. It also might be interesting to launch another study to see what happens to those motivation levels when only a few people prosper well from the efforts of many after motivating them using social engineering methods described in prior research.
