Labor has virtually no pricing power in the U.S. except in a few industries. Minimum wage laws and licensing laws are the cause of U.S. labor markets not being a truly free market.
Did you read the article? The author clearly paints a picture of too much pricing power in the hands of corporations and consolidations in business. Your counterpoint is the minimum wage is what prevents labor from being a truly free market? I can’t see how getting rid of one of the few protections for workers would make the labor market more free.
