If there is a labor shortage in the most expensive parts of the USA....consider the fact that many of your low to middle income service providers need to live further and further away from those most expensive places to live,
More than ever before.
Nearly 1 out of 5 people in the USA of 2014 were on food stamps and there was a so called "labor shortage" back then too.
There is no labor shortage, only a wage and benefits shortage.
