The whole idea that one country is the best is already ridiculous. There are plenty of countries that are well run and all have positives and negatives. I don't think to makes sense to pick a "best" country between the US, Canada and most European countries. They all can be good places to live.

Living in the US I definitely don't like that a lot of people here think that the US is the greatest nation on Earth. It's a mindset that blocks the country from learning from others and I think is doing a lot of damage (see health care and conditions for the poor). Interestingly people who have that mindset often never have been in another country for an extended time. The only thing they know is the US.
