Workers who put in more labor than others were not only paid more, but were also given various psychological benefits, e.g. famous workers like Stakhanov (who achieved an ungodly level of productivity at work) were made deputies to the Supreme Soviet of the USSR or to local SSRs (Russian, Ukrainian, Kazakh, etc.), were mentioned frequently in the newspapers as examples worthy of emulation, etc.
