As a Swiss citizen I don't understand how anyone from a first-world country would like to move to the USA. It's a downgrade in every aspect.
Giving up democracy, social-security, the practical absence of crime for a job in a country where every other Tuesday someone goes on a killing-spree, where people go to the doctor for moar Vicodine, where police will kill you for a donut. Nope.
Edit: changed englishman to briton. Thank you, commenters.
A UK citizen, probably, but I'd not assume that a guy named "McDowell" from Belfast is English.
The downside, of course, being the trade-offs you mention.
Northern-Irish, so technically a Briton, but not an Englishman.
Maybe they want to live somewhere that people have the freedom to build mosques with minarets and where nearly every women born in the country had suffrage for their whole lifetime?
Only from flyover America comes this constant trickle of reports of yet another female principal standing at the school door checking the hemlines of her charges. As for mosques with minarets, I saw this mosque (a big one) in a large Southern city that looked vaguely like a church, didn't have a minaret, didn't even mention that it was in fact a mosque, it just had a three-letter acronym on the side in green letters. This is a strong statement for a religion that actively seeks converts. John 8:7 please.
But, the US is a democracy by name. I'm not sure where you're coming from by saying it isn't.

As a European living in California (Orange County currently, but have spent some time in Silicon Valley too), I strongly disagree with that. Most parts of California are safer than my home country, and people definitely do not shoot each other "every Tuesday" (I know you were exaggerating, but still...)
