Do you really need additional clarification on why non-American citizen might choose not to travel to the US for literally any reason? If you do need examples, let me just gesture broadly to the entire US society.

Seconding what the other commenter is saying.

I’m in CA vacationing right now for a month, flew in last week. Literally the same experience getting in, and on the daily, as it’s been for the last decade of visiting annually.

I was talking to my +1 at work before I left, he’s just gotten back from living in OH for the last couple of years for his wife’s job. As much as stuff is seemingly a shit show at the highest levels (which we can all agree on, I reckon), the day to day hasn’t changed all that much. At least not for us privileged techies.

But hey, that’s just two datapoints, so what do I know really.

Not really. I even live in one of the cities that is "under siege". It's basically another day.

People read headlines, lock themselves in a cage of their own making, and assume the world is on fire. People would do better trusting their own eyes and ears.
