That can be a viable business model, but only for high end restaurants and bars. Providing good working conditions, benefits, and fair pay is expensive and those costs are passed on to the customer.

Jasper is a good example of this. They attract talent by offering a great work environment and fair pay/benefits but it costs an arm and a leg to drink there. If we want that kind of work environment to be the norm we have to be willing for those prices to be the norm. A lot of people are not willing to pay that price.
