First, let's get one thing straight. Nobody on the planet is more fiscally irresponsible (FR) than the democrats. They love to point at Trump, which is fair IMHO cuz he wasn't as FR as I and many other conservatives would have liked, but he still wasn't as ridiculous about spending as the democrats are/were. Almost every spending bill that he signed was higher than the GOP wanted, the democrats wanted the sun, the moon, and the stars in every frickin' spending bill that came up. There is a sizable GOP contingent in both chambers of the Congress that are FR, no matter who is in the WH. They wanted to spend much less on the COVID Relief Bills than the Dems did, and it didn't matter whether it was under Trump or Biden.
So, now it's a political issue, the Dem want to spend gobs of money that we ain't got and the GOP is going run against that. I think it's a good thing that SOMEBODY wants to rein in the out of control spending, and it sure as hell won't be the democrats so the issue should be up to the voters. It'd be nice if the 2 parties could do that in a bipartisan way, maybe not balance the budget but at least contain spending to like 3% growth year over year. But I think we all know that the democrats are not going to agree to that, and won't abide by it even if they signed up to it. It'll be interesting to see if we have a gov't shutdown over spending, and how that plays out with the voters next year.
And inflation appears to be rapidly rising, and interest payments are going to get really big. Some of that is intra-gov't, but most of it is not and pretty soon those IOUs that the SSA is holding are going to run out. Which means the intra-govt payments drop precipitously but the overall interest payments will continue to go up, both the principal and the interest rate. 10 years maybe, and then we're fucked. There's only one real way the Fed can't try to control inflation, and that's by constricting the money supply by raising the prime interest rates. And that means an economic contraction; we are a consumption economy and when the spending drops so does GDP. It ain't going to be pretty IMHO.
