I wonder what kind of skills are lacking. Claims of deficiencies are qualitative.

For example, how much math does somebody need to know for this kind of job? Is it trigonometry to find hypotenuses? Are they writing programs or entering in data to notepad?

This is an important distinction because we need to compare these skills to those of a shift manager at McDonald.

For example, at a hotel the shift manager must supervise the employees, handle money, and keep journal entries. The later two involve rudimentary mathematics and computer skills. There is a good chance that this is a fair wage when compared to similar jobs.
