That is your idea, not mine. The strawman arguments in this thread are strong.
I'd say litmus test benefits is a start.
You said "Let's cut it all", sorry if I didn't interpret that as a hyperbole. Considering the number of extremists on this forum I can never tell.
If you are referring to "means-testing" for SS & medicare then I agree that such a measure would help prolong the life of the SS & Medicare funds (perhaps indefinitely). However, it would not address our budgetary issues at present since they are unrelated to payroll tax programs.
To address our never-ending budget issues my pipe dream would be:
(a) simplify the hell out of the tax code, but keep it progressive. Pass a law that somehow requires extraordinary % of senate/house to introduce new exemptions and complications to code (probably needs constitutional amendment)
(b) Somehow have a bi-partisan independent agency run nothing but cost-benefit analyses on programs like tech investment/etc. For instance NASA was expensive but introduced many new technologies to the world. Another example would be a transportation link that builds economic development but may run at a net loss.
(c) Raise taxes on upper class to a level which creates a balanced budget. However, allow for surpluses in good times / deficits in bad times so we aren't always fucking around with tax rates.
(d) Address an ever-growing government with potentially unsustainable government employee benefits.
I don't think we can ever get rid of social programs otherwise Emergency waits will go from 24h to 100h+ with grannies lined up around the block without Medicare. However, there is probably ways to streamline it and get rid of levels of bureaucratic red-tape which increase the cost.
But, none of this will ever happen because politicians will always buy votes with an exemption riddled tax system, extreme benefit give-aways, and lowered tax rates.
