I think this will depend on what happens after Trump goes, given the sheer size and diversity of the economic base here. Not to be discounted, population growth is slowing to a crawl thanks to anti-immigration policies and demography, plus lifestyle changes among Americans. But I have pretty much lost hope that guardrails will be erected by Congress or via the Amendment process to ensure a Trumpian clone regardless of party continues can/will be removed if elected. I am not sure the democratic process as we have known it since Nixon survives this. The impeachment process was a fail-safe, and if elected representatives regardless of party abandon their oaths of offices and face no consequences, then it is that no longer, and the people have no between-elections protection. If that's the case, then I cannot blame the rest of the US's ally/trade partner base for losing faith and trust permanently, whether a little, a lot or all of it, and that cannot help the dollar as a reserve currency.
