You are not, you just have constant propaganda to that effect and you believe it because most of you never leave your country. And that is not just me personal opinion. Going over a (incomplete) sample of freedom indices listed on https://en.wikipedia.org/wiki/List_of_freedom_indices we have:
Not saying “US NUMBAH ONE” but those indexes are just biased to whatever the index creators prefer. I could make one that heavily indexes gun rights, lack of hate speech laws, gross income per capita, or even military strength and suddenly we’re number one if not close to it. It would be just as valid a ranking. In other words those lists are largely rubbish. Never mind they rarely break things down by demographics, preferring to look the other way.
The problem with what you choose and how you weigh it is exactly why I listed more than one index. And btw: I did not skip over any index because it lists the US as number one, I only skipped indices that require registration to get the PDF and such. Literally NONE of the indices I found has the US as number one.
