Anyone who has lived, worked, or traveled to London in the past 15 years, would probably observe quite a bit of successful immigration impact on the culture and overall health of the Capital. So, I don't know if that implies the headline is insightful or disregarding the reality on the ground (vs the Policy debate). The openess of any society (or firm, or clique, etc) is almost never on Economic grounds per-se. There is, for example, in every new-business hire (a purely economics decision) a great weight placed on 'fit' which is code for 'cultural fit' and more abstracty, 'fit in the hierarchy of power and ambition' that is this firm. Public policy on immigration (while it is a mess in the UK and the US) seems it would be better off to at least table this important consideration as legitmate, rather than otherwise not address it directly. What follows from that, is perhaps another discussion.
