"From Middle English appropriaten, borrowed from Latin appropriatus, past participle of approprio (“to make one's own”), from ad (“to”) + proprio (“to make one's own”), from proprius (“one's own, private”)."

So when you write, "when you give away money as tax cuts" it gives the impression that allowing people to keep more of their earnings is giving them things, it comes across as Orwellian. Legislation was passed, and signed into law. In the U.S., following the law is not giving people things, but income taxes are giving the federal government things (sometimes states too).

And if there are recession fears, the last thing you want to do is raise taxes. The problem is where the tax cuts are, not that they are tax cuts; you want to cut taxes on people who spend a high proportion of their income on consumption, not wealthy people who will sit on it.

As for the political impossibility of reversing tax cuts, in the case of cuts for the rich, this is not at all due to public pressure, but private pressure, and in that the impossibility of reversing tax cuts is no different from the impossibility of not enacting them. When politicians are more obligated to voters than donors, taxes on wealthy people will rise. There is zero pressure from voters to maintain tax cuts on wealthy people, other than general support for an entire package of tax cuts if very visible middle class subsidy is mixed in with them.
