This guy is delusional. Big time.
First of all - what that means?:
[level of living standards in United States is still a lot higher.]
I never heard about this expression - "level of living standards".Where it is derived from?<p>Now if we abandon PPP adjusted GDP we'll see that US is not that super-rich country - average GDP per capita places USA on 17th place, far behind many european countries.

Even Canada (that has been long time a laughstock of USA),
in fact has a tiny little difference in nominal GDP with USA - 1-2k$. 
So why nominal GDP of Canada is 2000$ less than American, but adjusted 8000$ less?.
Because Canada is a lot more equal society:
GINI (inequality) in Canada = 34 (little higher than european)
GINI in USA = 45 (average for African countries).
To maintain equality you need more taxes. So less left in pockets of consumers.<p>Now, let's move to hallucinations: "European unemployment rate is higher than American":
USA=10%
Norway=3.6%
Netherlands = 3.6%
Denmark=4.40%
Austria=4.8%<p>You want me continue??
