It's because it doesn't break the political and financial careers of the people who do in the civil service and the politicians. Once it does, you'll see it is not repeated.

Prop 13 in California is an amazing example of this, known as a third rail political issue because it "kills" the politicians who attack it directly. It doesn't even approach even getting put up as a proposition or bill directly. It has a tight feedback loop because the most mobilized voting class, the olds, feel it immediately and the Howard Jarvis Taxpayers Association mobilizes immediately also. So they go for it on the sides, for things like commercial property, or complicated to understand inheritance and so on.

So if you really want to fight back and be effective, you have to (politically) destroy the careers of those who do.

Prop 13, for those who don't know...
