What makes you think you haven't already gone?
You have a comparable social program for everyone we have, and even a couple we don't. Your taxes in many cases are higher (check out your real income tax rates) and your national debt of 5.9 trillion is nothing to ignore. Clinton was as hard on your military as O'Crouton has been on ours and what we have in French, you'll soon have in Spanish.
Some one mentioned "thought police" and laws against hurting someone's feelings. We have a law against distributing hate material, libel and slander, other than that, I'm not sure what that is about.
