It depends on the details. It’s certainly possible that more money in the hands of consumers, entrepreneurs, and investors will lead to growth that will have larger revenue generating effects than the apparent losses. It’s also possible that an initial round of spending reduction and tax reduction will encourage the public to support further changes in the future, including bigger cuts in spending - meaning it doesn’t have to all balance out at once right now. I do think that public appetite for this will grow - just purely based on the numbers, it seems inevitable that the US will end up revisiting Social Security, Medicare, and Medicaid. It’s painful but I think more people are recognizing this reality daily.
Coming back to the revenue reductions: the Trump 2.0 administration is very different than Trump 1.0, and he has a lot of smart, experienced people around him to advise him. I can envision them coming up with plans that are successful in putting America back on the right track. But I certainly don’t “trust” the plan by default, for the same reason you’re bringing up. At the same time, I don’t want to be too negative about it either - we just don’t know enough about it. And maybe that’s okay, since it can be useful for the administration to not reveal their larger strategy publicly for many reasons. So I can’t square it, but I am hopeful about where all this is going. Continuing the trajectory of the last several administrations is worse.
