No government in all of history has been perpetual.
Sometimes a short term loss or pain results in true progress. Failed government? Fire it (rebellion, revolution, insurrection per Declaration of Independence) and reset.
Our long term national problem is government-induced invasion and nutty citizenship policy. The leaders want it that way, at best they don’t care. They are in a globalist elite class. If they cared, they’d do something about it.
The USA is not a country in the classic sense of the word. I look at the USA more as an economic zone or more formally as the North American Economic Zone (NAEZ).
