You are like the coach of a sporting team pointing out all the teams that finished lower than yours on the ladder and saying "We did great compared to them. Good job. Keep it up."
Surely, if you were actually interested in improving your team, you would point out the teams that finished above you on the ladder and say "We can do better. Here's where to improve."
Somewhere along the line, America was so busy congratulating itself that it has forgotten it should be striving to do better.
You missed the point. Everyone knows the sports team that constantly finishes in the middle of field is better than those below. OK, we get it.
Why are you so concerned with comparing America to the countries that everyone knows are "lower" than America?
If you actually had any interest in improving, you'd be looking at those countries higher than America, and you'd notice the gap between America and the top of the ladder is growing very, very quickly.
