I think there's realistic doubt we can climb out of the hole. It's right deep. Unless government stops stymieing people who work, earn and hire, something I see zero (so to speak) sign of happening, it's not going to get better.
Assuming for the sake of the question that we can, however, no pol will say what would have to be done because all pols by definition want to get themselves elected, and if he's honest with the public he won't be. It's understandable. He can't accomplish anything without first doing that.
Fact is he can't accomplish much after doing it, either. People gain office only after having run on minimally relevant platforms, and the public is thereby unprepared to accept the policies that might help solve hard problems. Since we have a pluralistic political system with power placed in the hands of a number of representatives and institutions, they stalemate one another. Nothing of substantial effect gets done. We could live with that, in fact we could thrive with that, were government not the grossly fat parasitical monster it has become, but there you are. It is, and next to no pol I see is even talking about putting it on a serious diet.
