Does this happen in Williston, ND? The oil boom in that area has spurred so much growth that even entry-level workers at Wal-Mart are paid $17.40 an hour, or 2.5X the minimum wage. How many of those workers have signed noncompete agreements? I don't know for sure, but given the competition for labor there, I doubt that many have.

If this is a problem, it's just a reflection of market conditions (including high unemployment). Williston shows that the cure is growth. A rising tide lifts all boats.
