It will always be like this… until it isn’t. Your argument is tired. “The moment” eventually has to happen to force change. You take things like the 40 hour work week and weekends for granted, but people died in labor demonstrations and factory disasters to secure that comfort for us all. I pay my federal/state taxes and local levies, I support social safety net programs. These tips will not be the difference between someone eating or not, but it may be enough for them to force the ruling class to cede just a little more profit to the workers (or pressure the state to act against business of those social safety net programs are being more heavily utilized).
