What? This is not at all true. Maybe that's a belief that many Americans have, but the US passport is not one of the most prized passports in the world, there are about 30 other country's passport I'd rather have before having a US one, if you're talking about getting access to other countries with/without requiring a visa. A quick check of any of the "passport indexes" (Henley Passport Index, Arton Capital Passport Index) will show you that the US passport is fairly low ranked compared to the top ones.
Hard to take the rest of the article serious when it starts out with a serious flaw in the reasoning.
