Actually, as a non-EU national living in Norway but currently looking for (academic) jobs everywhere, continental European immigration policies are not that bad. I came to Norway as a highly skilled migrant, and the process was more or less painless; after three years, I got my permanent residence, also with very little ado. I did have to take a language test, but only for the permanent residence, whereas in the UK I have to demonstrate proficiency in English before I can apply for a temporary work permit, even under Tier 2 (skilled migration).
Europe does not have a great track for entrepreneurs (though hopefully that will change with the blue card program), but at least my experience with ordinary skilled migration is overwhelmingly positive. And anybody who thinks there is less bureaucracy in the developing world is highly likely to be living in a dream. At least in Russia the corruption comes on top of the ridiculous red tape.
As idiotic as US work/immigration policies are, most countries are far worse. Europe particularly. Commonwealth nations possibly excepted.
In the developing / BRIC world, it's less bureaucracy and far more petty (and not so petty) corruption you have to deal with.
