I cannot imagine most people reading this came away with this perspective. Clearly he is using the term colloquially as a stand in for stating that is what their labor is worth.
Again, I believe this is your conflation. He is clearly debunking the latter.
Do you deny unions have an effect on wages? If you do, they you should obviously concede the point that people are not always paid what the value of their work product is worth, nor what an employer independently thinks it’s worth. If you don’t, then why do you think people join unions, and why do you think conservatives are so against them?
No, he’s not. For example, a static wage in dollars is worth less every year. Are you saying that the value of one’s labor absent a raise declines despite increased experience on the job? Is every athlete paid an amount commensurate with the actual value of their labor? Why do celebrities, athletes, and high profile white collar workers hire agents to get better salaries if outcome in either case must axiomatically settle at the value of the work product of the individual? Why do almost all restaurants hire most new employees at the same wage? Do they just all coincidentally have the same value for their labor?
Here’s another real world example. I usually have to pay babysitters $15+/hour. Recently, when our normal sitter wasn’t available, someone recommended their sitter to me. She charged $12/hour. I was, and am, perfectly willing to pay more than her rate because her labor is actually worth that to me, but I only paid what she asked for. Why in the above scenario did the babysitter not get paid what her employer thought she was worth given my willingness, her comparable qualifications, and similar amount of “labor” being done?
All those scenarios above point out clear problems with the idea that your labor is worth what you are paid. Unless you just want to accept the above as a tautology, there are thousands of examples of situations where it doesn’t hold. Even something as simple as an athlete being paid while on IR. How can their labor be worth much when they are not actually producing anything? So if your side wants to continually argue this really stupid point, perhaps you can address the above. You don’t need to pick apart of short article by Reich to recognize how dumb this claim is.
