I should say it's not just the Brits (including the diaspora such as in the USA etc) of course. Here's a nice pic:
Africans love their church organisations and such as well for example, much more so than the British diaspora. Obviously it's all broad brush strokes, but to give a hypothetical example, you could probably fund a lot of healthcare costs in much of Africa by getting the churches to pay for it via donations etc, simply because of how many people go to them. The Anglosphere (and other) figures would probably be higher were it not for the large welfare states we have, which as many have noted in the past, tend to depress levels of civic engagement ("let's help the neighbours" becomes "it's the government's job", basically).
Still, interesting reading.

Well worth a read IMHO. It's all rather US-centric, but does show how messed up the US healthcare system is, with or without Obamacare.
