It actually does. But don't worry, pick any stat you associate with freedom. The US will rank below 40 compared to other nations, it will rank below 100 in many categories.
Nz being an ally of the US is a hold over from your imperialist colonialist past, nothing more. You've advanced beyond the US, as have a lot of nations. The only thing the US has over you is GDP, a stat not useful for much according to the inventor of GDP, and military spending.
Given what it uses that spending for I get why you'd be scared, being an island nation in the Pacific and all; but realistically they're not competent enough to invade you anymore. I mean they've lost every war they started since WWII.
Man I hope this is satire. It has to be satire.
