I lived in Switzerland for 2 years, where most workers are paid a living wage. A simple salad, pizza, bottle of wine dinner could easily cost $100 or more. The service was very good.
I am also in favor of paying people a living wage, but I am also aware of the fact that I would pay for it. We did not go out to eat frequently.
Is it your assertion that the cost of the meal in Switzerland was a direct result of the “living wage” vs tipping model of paying servers? I would challenge that assertion. I lived in and traveled through Germany, France, Belgium, UK, Eastonia, Russia, Denmark, Norway, Greece, Italy, Turkey, Spain, Czech Republic, Poland and many others and the price of going out varied wildly in each of the locations. (Norway was by far the most expensive, followed by UK). The cost of going out reflected many more factors, including the relative level of wealth in an nation, their tax structure, societal norms, and food costs. What was common to all of them was the practice of tipping not being the norm.
If we were to extend your argument to this thread I would interpret your assertion that moving to a model in the diving industry where DMs and crew about LOBs and other dive operations are paid fairly rather than using models that rely on tipping would drive the costs so high that people would rarely dive? Diving is a common enough hobby in Europe so that fear, on the face of it, would not appear to highly probable.
