The disgust is this: Any private company that provided lavish benefits like this would either change or would have gone under long ago.
But a government entity? Not responsible to shareholders, no need to make a profit, just address revenue shortfall by raising taxes using the votes of the very people whose benefits are so lavish. It’s a vicious circle.
As noted above even FDR was opposed to public sector unions as anyone can see where things will eventually end up.
Illinois is deep blue. They will figure it out. The voters there are cool with it. The other 49 states have absolutely no say in this.
