In the United States, the shortage is not of qualified technicians but rather a shortage qualified technicians who will work for the wages offered.
It's almost like the companies offering these positions are trying to make them non-career positions much like the line service jobs at most major chain FBOs.
I'm sure there are many exceptions but someone with A&P level abilities can easily jump right into making 22.00 a labor hour at a top car dealership with the ability to turn upwards of 100 labor hours in a 40 hour week with 60 hours being average.
