I've given several reasons here (non of them "racist", Joseph), and others elsewhere, why the world would be a better safer place if the UN agreed on the kind of Global Regualtionism I mention above - inluding economic immigration/emigration being illegalised. Yes, a lot of us are where we are in the world now due to the fact that it has been legal (if restricted) for many years - but that should NOT mean that we just have to continue to support it. Slave immigration/emigration was, of course, legal for a long time - it still goes on, e.g., for prostitution, but most are now heavily against it.
