The concept of labor being a commodity under capitalism is the opinion of Marx and Engels, so needless to say I'd be wary of adopting that idea.
Needless to say, the work you expend cannot be 'bought back' after you 'sell it', as compared to how you can buy back other material commodities. If labor is a commodity, it is fundamentally different from all others (from economic, legal, and practical standpoints).
Want a harder working employee? Pay more.
By this metric, those who are paid the most "work the most", when any anecdotal evidence will tell you that's not necessarily the case in terms of effort expended.
Sometimes, you can't pay people enough to overcome their laziness or unwillingness to work.
Lol. Tell that to my Econ 101 professor back in the day. He was no Marxist.
LOL. This is almost childish logic. Gasoline is a commodity that you can't buy back once you use it.
It is amazing their are Freepers, the R rock base, can't understand the concept of a free market for labor. Wow.
Fixed it.
