We're a small town, we need more people. Wait, not those people!!!

The problem is that everything is coming in so fast that the infastructure cannot handle it. No housing, grocery stores and restraunts can't keep up, the roads are getting destroyed, and city utilities are being overtaxed trying to keep up with the demand.
By the time all this catches up, the boom will be over and the money gone, so it will be a waste.
