I don't think they do -- it's pretty basic economics that price fixing and/or supply shocks can result in smaller net economic output. For a thought experiment: imagine if the price of a haircut was fixed by law at $500 (or that 99% of barbers suddenly died and the price naturally surged to $500). Enough people would start cutting their own hair at home that the entire haircut GDP and employment of the nation would go down. Even though the lucky few who still have jobs have excellent wages and there is still a steady supply of haircuts to rich people willing to pay $500 a pop.
