Interesting way of saying which are the countries where the most really wealthy people live, in theory at least. Because of course for large numbers of the wealthy, where they 'live' for tax purposes especially, can be quite different from where they dwell. Which does not of course help the trickle down theory, since people tend to spend where they dwell, not where their citizenship dwells.

Look at the country with the lowest Mean/Median "Australia"

They have the lowest Mean/Median because they have privatized their pension system.

If Americans included the Net Present Value of their future Social Security benefits, or if we privatized our government pension system, our Mean/Median would come way down too.

So according to this the average net wealth of american families is over $400,000..

With the massive amounts of Walmart workers and homeless people to drag that down the accumulation of wealth is unimaginable and completely unexceptable

Important distinction to understand,

That's because we are owned by the corporations. All those supporters of the present version of capitalism are not only screwing all of us, but the majority of the American people.
