And as much as I love that the NHS is a thing, it's not a reasonable comparison. No one I know who has a choice uses NHS services apart from emergency medicine or surgery. Everyone I know who can afford it has private health insurance anyway.
In general, everyone I know in this country either has serious family money or is downright poor by American standards. There really isn't much in between.
TO BE FAIR: it's generally much more pleasant to be poor in the UK than it is in the US. NHS is miles better than nothing, which is what many Americans have to deal with.
