What really makes me sad about stories like these is that people seem to expect something for nothing.
They are eating at the cheapest fast food joints they can find /shopping at the cheapest possible stores, yet they expect the people in them to be something other than the cheapest possible labor. You make decisions exclusively on cost so the businesses you patronize do the same in order to compete. Every aspect of the transaction contains the absolute minimum time, materials, quality, and care because that is what you demand. Why would someone who had any skills to set them apart from their competition continue to work in a job like that?
No, they are not expecting something for nothing.
They are paying a minimum amount, but they should at least get minimum work.
Adding up change is hardly higher function learning.
