I didn't say that. My point is that people who excel at their jobs should have the ability to be rewarded. Do you disagree?
You can still have tips but it shifts from basically every time to instances of truly exceptional performance.
That said, the biggest problem with most service type employees right now, and this sadly gets away from DD, but is the amount of hours they are being given to work. I know many people who only get 12-18 hours a week at their service job (and even worse, you can be sent home early or even called off if it's slow), and even in CA where minimum wage is $14.25, one cannot pay rent let alone earn a living or even hope to have or provide for a family.
