Yeah, if this article wanted to be remotely even-handed, examples are plentiful. How many times has the Laffer Curve been trotted out to claim that reducing taxes on rich people will increase receipts, only for it to not happen that way? Or social cuts rationalized for the purpose of balancing the books, only for the savings to be spent on reducing taxes for rich people, leaving the books unbalanced? The purpose of a system is what it does.
Of course, the article didn't want to be even handed. Its primary intent wasn't really to explore POSWID as a general concept that applies nearly everywhere in politics. Its purpose is what it did.
