The one-year success rate for restaurants has always been terrible with 60% out of business or in serious distress at one year. By year 5, 80% are out of business or in serious distress. Thin margins, lots of competition, difficulty with location selection, the need to embrace technology, and the fact that you actually have to be good at what you do is a recipe for failure.Restaurants are always failing. If a business can't sustain paying it's employees $16.28/hr in a high COLA then they don't have a viable business model.
To your second point, the minimum wage here is $16.50 and restaurants are still open. While some have closed, it was because they were terrible - bad food, bad service, bad ambiance in the restaurant, etc, etc, etc.
