Not sure how I missed this one. The story in the original post narrates a predictable response by business when the minimum wage is tinkered with.
Regardless of what the law says your time is worth, the value of your labor is what the company gets in return for your paycheck. When the minimum wage is raised the company will, very predictably, find innovative ways to restore the balance (in their eyes) between what work is being done and what wages are being paid.
Firing, or not hiring, those whose training and skills are now not worth what they must be paid is predictable. Compelling the higher paid employees to do the low skill tasks in addition to their own (more work--same pay) is also predictable. Finally, the higher unemployment creates downward wage pressure (more work--less pay).
Minimum wage laws are a bad deal for everybody.
