rowingengineer, I studied statistics at the graduate level so I am well aware of the distribution of IQ and all that jazz. I have met some imports here that are very bright and some not so bright. I can't comment on how the not so bright arrived in the US because I am not part of that process nor have I read anything about it.
The USA is my primary concern. I have family members and friends who are digging exceptionally deep to stay afloat in this recession. I have helped some of them with my time and money for about 2 years now. It's not been easy for me either because I've been more unemployed over the last 2.5 years than employed. That means I am digging deep, too. So, why would I care about any other country and their citizens coming to the USA to work, when we need to be working in our chosen fields and continuing to progress?
I am not being sarcastic or cold but very realistic. Some are looking at having everything they've worked for the last 30+ years wiped out because of this recession. I may be amongst them. Those are sobering thoughts and positions to view the rest of your life with and from. It stinks, when you've been responsible, worked hard, lived well within your means, and saved. I don't even own a TV.
Further, I met two Brits who are working here, who criticized the USA openly and vehemently every chance they got. Their two beefs with us: 1) We didn't enter WWII quickly enough, and 2) We are energy hogs and we should be solving China's problems with poverty and energy.
Needless to say, since my dad and uncles served in WWII, their rants about our late entry into that war didn't impress me favorably. One uncle took a bullet that sent him home. I've heard other imports talk disparagingly about the USA and its citizens as being pretty darn stupid, greedy, unethical, etc. That does not make points with me either. If people don't like it here, they are free to leave. When I've been abroad, I didn't complain about anything. People are different and have different ways of doing things. So what? That's life and I enjoy life.
When I went to Paris, the French treated me like a second class citizen because I don't know French. Didn't bother me one bit. I was just glad to be there!
I love people but some can be a real challenge and require a lot of patience. Usually, they're worth it.
