I read through your comment twice and am still confused why it’s puzzling that Americans would travel to Asia for the local markets. If it’s cheaper, and the same or similar quality, why wouldn’t they?
My intended meaning was that it is puzzling why Americans ostensibly tolerate policies which eliminate those markets, but only after they come back.
But, how do you know that the same Americans traveling to Asia are also tolerating said policies/politicians? I've had the same next door neighbors for 15+ years, and I have no idea what policies/politicians they tolerate/support. Much less the random person walking down the street.
I'm speaking from personal experience. I have travelled a lot, and I've noticed this as a pattern over what must be hundreds of people I've talked to at this point. I don't really know if my sample is indicative of the US population--I'm just puzzled by what I've seen.
