If I buy a machine, then hire a worker to make a widget. And I sell that widget for $20 but pay him $10 is that fair? The machine, shipping, sales, marketing, inventory arent free.
I'm a pretty dyed in the wool anarchist, and I'd say most leftists would say, "of course costs for capital should be considered in prices." The objection is when your costs are $5 for non labor, $10 for labor and you sell the part for $20. Where's that excess value going? Maybe once the costs of the machines are paid off, the workers should all get raises, right?
