There is a lot of talk about how people who get tips generally get a very low wage to start and if they don't get good tips they make a lot less. The federal minimum wage is $7.25 per hour (effective July 24, 2009).[1] Furthermore, the federal government requires a wage of at least $2.13 per hour be paid to employees that receive at least $30 per month in tips. If wages and tips do not equal the federal minimum wage…
Is minimum wage a living wage? $7.25 * 44 hours per week * 51 weeks per year is still only 15,950 US$ That's gross, not net. I'm not convinced that people would pay extra even if they didn't have to tip to a company that paid a living wage but charged more.
Probably could be a really interesting research topic but Uber comes to mind as part of the reason I loved it at the beginning was the lack of tipping.
