the tipping situation sucks, but the larger economic problem is effectively due to rent extraction by the landlord. when a restaurant can't afford the rent that, say, a bank can, they are effectively priced out of the market. All excess returns and up going to the land owner. This effectively becomes a variant of baumol's cost disease. Once again, return on capital trumps return on labor.
I remember, many years ago, living in Manhattan: in a short period of time, for restaurants on each corner of an intersection were replaced with four banks. A vibrant spot died.
