My daughter makes 15 an hour rolling burritos. Why should restaurants that charge a lot more for meals pay their staff 2.19 an hour? My duaughter also gets tips split and its just icing on the cake vs something she has to bank. Meanwhile, at a lot of these restaurants that fail - the owners absolutely THRIVED while screwing over pay and once that scheme was busted, its not the employees fault for not wanting to be a part of it. This re-balance was long over due since the feds and states have not done much to keep up with livable wages themselves (at the pressue of businesses who said it would hurt them)
