The cake it already baked as it is, yeah let's just pour more on top. Right now around 8% interest rates held steady for just a few years would mean half our tax revenues going to pay interest.
That doesn't account for a recession if revenues plunge like they did in the last one. Add $5T more in debt and it will only take around 5% rates to accomplish the same.
We are rapidly closing in on the point where even low historical rates will bust our budget to the point where we can't even meet half our current obligations. Being the bulk of the budget is social programs and military, think about the consequences of that. None of that even accounts for unfunded liabilities and state and local spending and debt.
