Its an interesting notion, only paying somebody what they need to live on.
The Capitalist class would love it, think of the increased profits. Then though its possible I would agree with the notion, in a Communist society where goods were plentiful and distributed according to need, there would be no need to pay more than what people need to live on and the extra could be used for societal rather than individual benefit.
Quite by accident I think
@Bluemanc100 has highlighted a notion that is well worthy of discussion.
