Off The Books
Has anyone else noticed the proliferation of "tip jars" in strange places? I'm now seeing them at fast-food joints, movie theater refreshment counters, the corner grocery store, and even car rental desks. My dry cleaner has one.
Several factors are behind this. But essentially it's a response to a stagflationary environment in which wages aren't keeping pace with the cost of living. Of course it contributes to a vicious circle, because when income that would have been taxed stays off the books, generally the government either raises taxes or prints more money (the latter is presently the case) which in turn increases the cost of living. Incidentally, keeping income on the books and thus in the system is one benefit of raising the minimum wage.
When you start seeing tip jars next to the cockpit when leaving an airplane, you'll know we've reached some sort of breaking point.
