Part of the reason why billionaires are cozying up to Trump is that Donald Trump is the most worker-hostile president in the United States in a century. Trump has open contempt for America’s workers, and he is allowing the billionaire class to run wild in their effort to replace as many of them as possible, so they can make more money. Bezos might not be alarmed by the Sanders letter today, but if Democrats win back the Senate majority next year, Bernie Sanders will be a committee chairman, and he will be calling Bezos to testify before Congress.
