Here's my question, though: Doesn't somebody have to buy the burger? Who are the burger-flippers selling burgers to -- other burger-flippers?

In some parts, yes. In some areas, the job base is overwhelmingly service positions paying little more than minimum wage.

"In some areas, the job base is overwhelmingly service positions paying little more than minimum wage."

If minimum wage service jobs are being created, somebody's gotta be buying the services. Otherwise, the creation of these low paying service jobs doesn't make sense.
