Obviously not every other country is the same. The situation is not that the US does everything one way, and the entire rest of the world does it another way; there are about 200 different countries, and they all do things differently in some ways. Some countries get most things right, some get most things wrong, but most countries get some things right and some things wrong.

There's a lot to learn and improve by looking at how other countries solve their problems.

This was also the topic of Michael Moore's Where To Invade Next. Instead of taking other countries' oil, the US should take other countries' ideas, and Moore had a couple of suggestions for interesting ideas from other countries, like school lunches from France, prison system from Norway, etc.
