Actually we are around the 13th highest when it comes to our poverty line, considering pretax take home pay before assistance. Ironically, given this thread, there are lower poverty rates in Scandinavian countries who do identify themselves with socialism.
Of the 26 countries, the United States ties for the 13th highest pre-T&T poverty rate, which stands at 28.4%. The countries with the lowest pre-T&T poverty rates are Korea, Iceland, Denmark, the Netherlands, and Norway, with pre-T&T poverty rates spanning from 17.3% to 25.7%. At 35%, Spain has the highest pre-T&T poverty rate.
If you google the happiest countries in the world, the top ones are mostly in Scandinavia. I think Australia and Canada are in there somewhere as well.
