Humans according to studies are activated not motivated entirely by money but by the work they're doing. A macdonald's employee wouldn't take their job as seriously as a CEO would for example.

This could be a form of socialism which can turned out bad if placed in the wrong hands. Sure socialism without currency and being provided for sounds like a great idea but it could turn into a form of communism like china if someone pulls the string.
