I think we're in for some very tumultuous times in the US and we could see a paradigm shift in our political system as a result.
Clearly, there is natural trend towards increasing wealth redistribution and keeping welfare systems in tact, while keeping taxes relatively low. However mathematics show that we will be forced to either raise taxes aggressively or reduce benefits.
One way or another, this thing will break heavily to one side, IMO. I'm not sure how it will play out, but it will be interesting.
Everyone says they want less government spending and lower taxes, but as soon as you cut a small fraction of the government (17% of workforce in non-essential roles) people freak out. I can honestly say I can't even tell there is a "shut down" and yet people are loosing their minds.
Anytime you actually put names and numbers of programs that you propose cutting, people are against it. So when they say they want lower spending, they don't really mean it.
The tipping point will likely be when we can no longer borrow affordably. That is when the rubber meets the road. Do we raise taxes to extreme levels in order to pay for our spending, or do we reduce spending.
Taxing the rich into oblivion won't work long term, but they will try that first.
