That whole attitude of being "the greatest country in the world" always seemed so peculiar to me. I get that all countries tend to be patriotic and embellish themselves but that just sounds a bit ridiculous and antagonistic. For a country established by immigrants and populated by immigrants, you'd think the national identity would be a bit more versatile.
Instead, it's been homogenized to the point where people have to fight their own perceptions to reclaim their culture and identity. It's a shame, really.
