This is nowhere close to reality. Yes, we have more radicalism - but that on the right was a response to that on the left. Conspiracy theories abound on both sides (such as that Trump colluded with Russia during the 2022 campaign, or that hundreds of thousands of ballots were lost or stolen or changed or whatever to turn the presidency over to Democrats in 2020.

And for some reason, the left uses "populism" as a pejorative term (except when they use the same tactics). Populism is just one part of Democracy, and wanes and fades with time.

Also, "far right" in the US really is the pejorative term for what used to just be called "the right" - with some notable exceptions who have become more radical, mirroring the left.

But we are nowhere near Russia in terms of social or political dysfunction, not even close, in terms of potential for all the things that cause a mass exodus.

Even during Vietnam, when many realistically feared conscription, we lost only a negligible number of people to emigration. In contrast, many more of us volunteered and served in that war. And that was a far more radical time, with far left groups doing about 1000 bombings per year, plus arson and other unrest, plus a rapid, 20 year rise in violent crime.
