“how is it any particular form of “entitlement” for people to demand that they have *something* to show for their work?” — Ms. Jane was getting “something”: a paycheck and pretty generous benefits. Her predicament is entirely the result of her choices, not Yelp’s. The fact is, her salary exactly equates to what the market will bear in San Francisco; if there is a shortage of people willing to work for what the job is worth, the rate will go up or perhaps customer-service people will be outsourced (as it sounds like will happen). This is how economies work.
No one forces you, as a user, to use Yelp. No one forces employees to work there. If you find their hiring practices abhorrent, don’t use the service. If you think their employees are so wonderful, hire them away from Yelp. (This is, in fact, what happens to highly qualified employees in the Valley, not necessarily to 25-year-old Literature majors in their first real job, though.)
One of the reasons why S.F. is so expensive to live is because of rent control and other policies, not free market economics.
