There's no turning back, it will take at least another 15-20 years of constant work building trust for the US to get back to its standing pre-2025.
People like to heap the blame on the little guy, but what you say is also true of the elites that went all-in on offshoring and globalization.
A lot of the howling is from people mad their business empires are going to be hurt, who demand their interests be cared for after they were cold and uncaring to others.
I don't even know what the question is. Is there a threshold function? Is there a critical mass of stupidity beyond which all hope is lost and we just have to go through the ugly process of tyranny and its eventual collapse? But what if technology can provide a superior tyranny, in effect flawless totalitarianism? The hope part of the puzzle seems unpredictable.
[1] Bonhöffer seems apt here, a Lutheran pastor killed by the Nazis, who consider stupidity a greater threat to good than evil.
It's a kind of theatre whereby we elect certain representatives but the vast bulk of the government bureaucracy stays the same.
Trump and Co. are testing/challenging that system in a way: they are trying to wrestle power away from that immovable mountain of bureaucracy, into the hands of the elected government, and that bureaucracy, used to taking their immovability for granted (along with their jobs and budget money) isn't liking it.
A president can veto a bill passed by Congress. It doesn't become law. The Congress can override the veto and it does become law, that any law obligates the president. Not even in the most extreme case of the unitary executive hypothesis can a president legitimately ignore the law.
The bureaucracy is a creation of Congress. The president can veto budgets passed by Congress until there is a compromise.
It's not legitimate to call only the president elected government as if the Congress has no say.
Sure, there are statutes and chargers and oath sworn and whatever.
