I agree, but it doesn't reflect common sense. The common sensical thing to do would be to have an immigration "time-out" for at least ten years, and then institute immigration policies of no more than $100,000 per year, whereby the majority are from European countries, and a much smaller amount from the rest of the world.
You're right of course, but I would actually go further.
In the current historical context, where we have the Welfare State, Affirmative Action, and Multiculturalism within, and the Islamic fandamentalists without, I think the best choice is closing the borders to all immigrants period -- until further notice.
fundamentalists... good grief...
