Because women account for the majority of workers in tipped occupations - and because jobs that rely on tips tend to pay less than other occupations - most of the workers who would benefit from an increase in the tipped minimum wage are women. While women account for 55 percent of all workers who would benefit from a proposed minimum wage increase, they account for three-quarters of all workers in predominantly tipped occupations who would benefit.

We are talking about single mothers, students or the undereducated who have a hard time making ends meet, this would benefit them the most.
