It's not proof, but it's telling: it's the same reason sales tax is not included in the price of an item, unlike VAT in Europe. They want you to know how much you're paying.

This happens in other spheres. Two that come to mind are death penalty cases, where opponents play for delay after delay, and divorce court, which is designed to be horrible for everyone, and therefore limit the number of divorces. I'm sure something similar happens to abortion clinics when there is a sizable resistance to them.
