At least 8.5/10.
We are, in fact, freer in almost every line of rights than the vast majority of the world, plus we are still the richest despite massive debt, and still, if I haven't fallen behind the times, the largest GDP in the world. In addition, despite an economic recession (shame on you who would consider the situation as bad as the Great Depression; Yes, I've heard whining that would equate today's market to that of the 1930's) the economy of the United States is as far as my unprofessional eyes can tell nowhere near collapse.
Also, we answer the call more often than not for the most powerful nation in the history of civilization (we really are, not even Rome or Great Britain enjoyed such economic or military superiority/domination) with the most resources of any nation in the world to go out and uphold regional stability, the Geneva Convention, and all that. Yes, we've copped out when the situation does not favor a successful operation, but otherwise we rattle our saber in the right direction.
