It's unclear if getting rid of tipping would benefit all servers:
McKenzie conducted an informal survey of waitstaff at casual table-service restaurants to find out how they'd feel about foregoing tipped wages in favor of a flat hourly rate; he says "the wage that the restaurant servers indicated would be acceptable was in the range of $30 an hour, not $15 which is the wage rate states are considering," implying that such workers would actually be taking a hefty pay cut if the tipping model was ousted in favor of $15 an hour.
Tipping has an ugly history in the United States. The practice began with the European aristocracy and spread to the United States, where it became enmeshed with racial issues.
The racialized element of the practice continues to this day: 53 percent of tipped workers in New York State are minorities, and 21 percent live at or below the poverty line. And most tipped workers are not fancy steakhouse servers; they are women working at places like IHOP, Applebee’s and Olive Garden. Based on American Community Survey data, the Restaurant Opportunities Centers United estimates that nearly 70 percent of tipped restaurant workers are women, 40 percent of whom are mothers.
