I don't think this is a good Skeptics.SE question, but I would appreciate peer-review:

> A middle-class citizen in Finland owns $122 for every billion dollars of his or her nation's wealth. In Canada, it's $13. In the USA today it's only 60 cents. Thanks GOP for 30 years of trickle-down economics.

Now that's a silly metric, right? It is totally dominated by population count. (Finland: 5m, USA 316m)

Using reductio ad absurdum, a middle-class citizen in my bathroom owns ONE BILLION DOLLARS for every billion dollars or his or her room's wealth.

I think you're right, although ("middle-class citizen") it's also influenced by the GINI coefficient. I find it vague too, e.g. I don't know what "national wealth" means ... most nations have national debt.
