You forgot the US is also the highest % of single parent children in developed nations. We're the only developed nation that has no mandated paid vacation or maternity leave, and the average offered vacation/maternity leave is much lower than our peers. We have some of the highest # of hours worked annually for full time (except for Asian countries). The highest health care costs not only as a % of GDP but also per capita, for what we're quickly learning is mediocre care (and getting worse). We have very high infant morality rates and low life spans compared to other developed nations. The highest secondary education costs for what is arguably sub-par. We also have some of the most lax restrictions on chemicals and pesticides used on/in foods so we consume.
Its not all bad though, we beat most countries in food, taxes, utilities, and gas prices (even when it was $4 a gallon)! Also while the European countries might only work about 1500 hours a year to our 1700 for full time, those Asian countries are well over 2200 so it could be worse!
Of course if you don't like it you are free to leavebut it's interesting because we as Americans continue to have this belief that we are the best country by far, have the best of everything, excel at everything, and that was probably true until the 80-90's, but since then we've been complacent and everyone else has been catching up and in some cases surpassing us, for example China is now the #1 economy etc.
Funnily enough, as a nation we don't really excel (in the sense that we are really the best at) hardly anything. Number of serial killers produced and number of citizens incarcerated being the possible exceptions

I've been to a number of places I've enjoyed just as much, in some cases more. Didn't always have the best knife laws but, other than that, there are some great countries out there. And they even have freedom!
