I learned in freshman economics that flat taxes such as sales taxes are the most regressive of taxes. The reasoning is this: poorer taxpayers pay a greater percent of their income, and the poorer the taxpayer, the greater the percent going to taxes.
Once I found the main idea of Dan Fagan's recent column (it was lurking down in the body), I discovered that he didn't know the meaning of the word "regressive." Please buy the man a dictionary, or maybe he could even take Economics 101.
Here's another idea: don't send the ignorant to teach us. We deserve better. A lot better.
