Yes , actually statement if I will get more I will work more is not that correct . It ' s rather if you pay more you ' ll get better workers and eventually do more . That is why filthy greedy capitalists pay more for some people , while they also have like all other tools to motivate and would like so much to make motivation better and cheaper . Also people want to get the best compensation for what they do . Do you really need experiment to back up that ? Hell , even socialists advertise socialism in a way you ' ll get more for what you do cuz expluitatiun . That is why socialism failed time and again . They eventually get bad lazy people on responsible positions , that do not give a fuck for the work done . And if the best compensation is not even theoretically for the best work , then it is for something else . And in fact in soviet socialism people were concentrating their efforts on doing that something else . Here , for example , they wanted jobs closer to the goods distribution shop managers and even cashiers , those were much valued and really hard to get .
