Wage increases require both difficulty in hiring someone at a lower price as well as a need to do the job at a higher price.

50-year low unemployment may affect the former, but that does not mean that the jobs are worth doing at a higher rate. Like with the price of anything, there is always a point where something is no longer worth buying. A job may pencil out at $10/hr, but not $11/hr, and so as soon as wage pressure pushes for $11/hr, the job potential simply disappears.
