Superpower in what sense? I mean, I think I know what sense you mean, but there are some glaring socioeconomic inconsistencies with the label "superpower":
They sure do. We are not a superpower when it comes to how many people we put in prison. We are not a superpower when it comes to how many children die poor on our streets.
And we're not a superpower when it comes to ensuring that our population doesn't die due to lack of health care while driving up the costs for everyone else.
Each one of the issues I bring up occur because of market forces. Prisons are a booming industry (see Arizona's state prisons). Poverty has many ties to health care being market-driven as well as education.
But you don't seem interested in refuting any of my points, so I guess we're done here.
