So your argument is that these statistics "prove" that Sweden and Germany's people are worse off than the citizens of most US states?
First, it would seem that all those people are too ignorant to understand how much better their lives would be if they were, for example, living in Michigan. If only we could teach them how unhappy they are!
Second, the claim that the people are "poorer" is not a cogent claim that their countries are failures. Your argument reminds me of something I tell my children:
"Human beings are the most successful form of life on Earth, by all the metrics that humans choose to measure success."
they would be amongst the poorest states by median household income, purchasing power parity, cost of living, and gdp per capita
