Donald Trump has chosen a fast-food executive, Andy Puzder, to be his Labor Secretary. Puzder, the C.E.O. of the parent company of the Carl’s Jr. and Hardee’s burger chains, was a heavy donor to the Trump campaign. He is a prominent opponent of raising the minimum wage, of paid sick leave, of efforts to raise the salary threshold for overtime pay, and of Obamacare. Puzder is even critical of the federal relief programs, such as food stamps, that subsidize the poverty wages that he pays his employees.
