The second part of the story is that the US is richer than Europe. I moved to the US from Western Europe. Before I moved here I didn't expect how much more everything is more expensive here, but at the same time salaries are also higher. The US's GDP per capita is $62k, Germany's is $47k. But that doesn't tell full story. In the US there is a big difference between low paying and high paying jobs, rural and urban areas.
