Just as a fun thought experiment, let's say we price all the service workers at current income levels out of the market so they all move away. At some point, people will be willing to pay more for service work due to a strong demand for limited services.

It almost seems pernicious to have low income housing since it allows employers to get away with lower wages to cover an artificially low cost of housing, at the same time, service workers retain a poor quality of life because outside housing everything else is expensive.
