If you follow my first link, you can see the author's analysis is demographically neutralized (it excludes 1st and 2nd generation immigrants in European countries, and compares to white Americans). In this ranking, American whites substantially outperform the European average, and only 2 small European countries (Switzerland and Finland) noticeably outrank American whites. US whites are outscoring the EU-15 (basically the core nations of the EU, before it expanded into Eastern Europe), by a substantial amount.

The second image is not demographically neutralized, but European countries have far, far lower non-white percentages than the United States. For example, Germany is about 10% non-white as of 2010.
