Any benefit for which there is a wealthy constituency will not be touched. Until we fix our corrupt political system, any assumptions of "shared sacrifice" are fairy tales.
I just assume that going forward we basically have two ratchets. The one ratchet keeps getting nudged in the direction of giving more goodies to rich people, and except for possible temporary blips, those goodies aren't going away.
The other ratchet gets nudged in the direction of fewer goodies for the rest of us. And once gone, they're gone for good.
