In the case of the tip rule, Donald Trump has delivered a huge gift to the owners of big chain restaurants, for whom getting their hands on workers' tips has been a holy grail for a very long time. In Donald Trump, they finally found a president who will do their bidding.

Evidence shows that even now, when it is illegal for employers to pocket tips, many still do. Research on workers in three large U.S. cities found that 12 percent of tipped workers had tips stolen by their employers or supervisors. With that much illegal tip theft taking place, it's clear that when employers can legally pocket the tips, many will.
