There are 330 million people in the US that we know of. There are 12,500 school districts, 18,000 police departments, 17,000 libraries, 400 different languages spoken, 45,000 flights per day, 5 million privately and commercially owned vehicles, 200,000 dentists, and 641 amusement parks. 

There are nation-states (Japan, Korea), multi-state nations (Saudi Arabia, Jordan, Kuwait), and multi-nation states (US, UK). The US is probably the most pluralistic and diverse nation on the planet, especially in these numbers. Comparing us to Denmark, Thailand, or New Zealand is plain silly. I'm not disparaging those nations; I've been to them and another 60 besides, and like almost all of them (apparently, I'm alone in finding Iceland totally boring and Brazil scary).

It's like saying if a hybrid Kia can get 60 miles to the gallon, why can't a Ford pickup? Well, because they're entirely different vehicles with different appeals and purposes.

I pointed out to a client in Denmark while arguing these points that there are no lines of people at Denmark's borders seeking entry and citizenship. "Well, you're right about that," he said, "and if there were, we wouldn't let them in."

There's a lot of room for improvement in the US, and, in all fairness, there's been a lot of improvement, and people are better off than they think they are because they haven't been to 60 other countries (and, in many cases, even one) and they're drowned in bad news by media that reports calamity where none exists and refrains from reporting good news as if that's the calamity.

By the way, there are 2,700 commercial news channels in the US, and I'm not sure that's a good category to be leading (we're 4th, after Russia, China, and the EU).
