Earlier quoted context omitted.
I live in California and this isn't true here. All restaurant workers receive at least minimum wage before tips. In my city, that's $19/hour with health insurance. Of course, you're still expected to leave a tip and suggested minimum is now 20%, plus even McDonalds is charging $15 for a 4 oz burger, so I rarely go out to eat at places that expect a tip anymore. I'm not sure why they specifically should be tax exempt…
I'm happy that CA doesn't set a lower min wage for tipped workers, but the problem is that in many/most places in CA, $19/hr is still not a living wage, so the tips are more or less required to keep those workers housed and eating. A living wage in most population centers in CA is nearly $30/hr.
I have to ask what is causing what's considered a living wage to increase so rapidly, because it appears to be increasing far faster than the national inflation rate.
It sounds like a wage-price spiral, though I'm not aware of anyone claiming we're in one.
