Which government in history has not been immoral in practice?
The US government is one where most of society shares moral responsibility for its acts of immorality.
If one argues, say, that the prison-industrial complex, and things like marijuana prohibition, are morally wrong, then the people who vote for the politicians and judges and sheriffs who make and enforce the laws are morally responsible. Therefore these people deserve to suffer from a degree of economic hardship that is partly the result of this immoral system they voted for.
If one argues, say, that the government's wealth-transfer schemes are a form of theft from the productive to the unproductive, and are morally wrong, then the people who voted for the new taxes and regulations etc. deserve to suffer from the economic hardships.
If one believes America's moral fiber is decrepit, and Americans continue voting for immoral policies on both left and right, then to what extent this is true Americans deserve to suffer the consequences.
I of course believe that Americans are good people, that America is overall good and that overall the American people are good, decent, and patriotic, and that despite their differences both Liberal, Conservative, and libertarian voters and politicians are decent people who love their country. THey all have moral flaws (thus allowing for nonsense like the Patriot Act or, say, Chicago PD black sites to exist), but overall I believe America is decent and good.
This is why I don't believe the American Republic will collapse. I believe in America. All my predictions on this forum and elsewhere are based on my belief in:
1. Humanity.
2. America.
3. Freedom.
America will not collapse, the Republic will continue, the people predicting doom and gloom will be wrong again. People who bet against America are always wrong.
