THE MARKET DOES set the wage: it has decided that tipping on a merit system will be the wage. I know in your cloistered academic world of being a gummint employee
you have zero concept of the free market. Your wage isn't set by the market. It's no doubt too damned high. You don't understand anything about the market
..or as txhurl said, how tipping infuses "the DNA of capitalism" into the food/bev industry. And it does, at every level.
Well said!
