Is that not also true for any increase in costs for the owner? The minimum wage has been static for 12 years yet costs have still gone up because the owner passes those costs on. Wages are no different.
We actually agree on something. Weird...
But the cost of most goods and services has gone down since 2009. Really, the only services whose prices have gone up faster than wages since 2009 have been medical care, college tuition and textbooks, and child care. Housing and food have also gone up, but slower than wages.
In other words, the only goods and services whose prices have actually increased since the late 90s have been those in markets with the most government interference. Everything else—basically, everything that is actually subject to a free market—is the same price or cheaper than it was in 2009.
