Just to clarify it looks like that chart has a number of specifically chosen countries. I'd suggest you add some more western countries with socialized medicine - Canada is well above the US as is the UK and I think those are both pretty comparable to the US in terms of personal wealth... Oh also Sweden is well above, but Sweden tends to be an outlier due to just how well socialism is working there.
