“One is sustainable, one isn’t.”
That’s simply not true. Neither method of funding the spending is sustainable when the spending itself is unsustainable - which it clearly is.
Tautology aside, I don't think they're equivalent methods.
Raising taxes to match the level of spending will force the voters to face a (painful) choice today. Pay more in taxes or accept a reduction in benefits.
Debt financing, which has been our history, let's us believe that we can spend whatever we want and have tax cuts, because the pain of too much debt is felt down the road.
Frankly, that's exactly what Trump and the Congress are doing. Surely you've seen the projections after the tax and spending bills?
You say Trump is working on a long term solution but I sure haven't seen any evidence of it.
