what is “labor” that is this commodity? i know what a log is, you can weigh it and characterize it. i don’t know what “labor” is prior to some kind of social definition. we have a variety of legal institutions (hourly worker, independent contractor, salaried employee, sole proprietor) that involve remunerating human work. there are other historically common labor institutions we forbid. what exactly is it you think markets can fruitfully price?
