And, did you bother to read the article? I'm surprised you write off these regulations for expats as 'rich-people problems'.
So yes, rich-people's problems.
I really don't get your point. So, if you are 'rich enough' (note: the people in this article are solidly middle-class) to actually maybe be affected by and give a shit which passport you've got, your opinions are immediately written off as 'rich people problems'. On the other hand if you're among the poor in the developing world and your passport is perhaps not something you'll ever think about or care about, then because maybe according to jessriedel you might prefer a US passport to e.g. a French one or a Swedish one or whatever, the US passport is 'the most coveted in the world'. Despite (apparently too rich to count) people giving them up in record numbers.
I'm fascinated to hear other opinions you hold on random shit, if this is any indication of how you arrive at your conclusions. Do tell.
Extensive nation-hopping is not something most folks in the world can do. (The "onerous tax filing" being even more of a rich-person's problem.) I'd guess that the US citizenship is in fact the most coveted worldwide, all things considered.
