The starting pay has a lot to do with where you are. Here in Eastern Carolina, $10 an hour will have your phone ringing off the hook with people looking for that good paying job. Up in Maryland where I came from, $10 an hour won't even get you one call. You can buy a older 3 bed/2 bath house on 1/4 acre for $125k give or take here in Eastern Carolina. In Maryland the same house costs twice as much money. House rentals run the same way.
It's all about what it costs to live. Almost every one of these people are only looking for a job because they have to. They have bills to pay. They have no real expectations of ever having a million dollars. If you have bills that require you to have a job that pays $15 an hour, truthfully, why would you work for $10 an hour? If you c an pay your bills on $10 an hour, why not take the job.
You see, you guys all think you set the wages. You DON"T. The wages are set by the local economy. If you don't pay enough money, then you will have high employee turnover or even difficulty finding help. If your wages are right then your employees will tend to hang around longer.
Guys in high cost of living areas will ALWAYS pay more money. But you guys shouldn't look down on the lower cost area's wages. It's just the market setting the wages.
