> Of course this means that the next administration will need to start with tax increases just to get to neutral, but maybe that is a feature?

Oh no.

What you have missed is the incredible end run around the spirit of the reconciliation process that the Republicans did this time around.

So, the did these tricks with the tax in Trump's first term, with tax breaks set to sunset in order to have a revenue-neutral effect over the required ten years.

This time around they needed to extend those breaks, right? So they must had to cut spending or raise other taxes in order to do that and have a revenue-neutral effect, right?

Ha ha, no! They convinced the CBO that the baseline for the reconciliation process this time should be whatever was in effect for the last few years. So those breaks are already baked in and don't need to be counterbalanced. It's a two-step, long-term process for making things permanent through the reconciliation process that otherwise one could not.
