capitalism = "\u{1F1FA}\u{1F1F8}" # US flag
# => "🇺🇸"
opposite_of_capitalism = capitalism.reverse
# => "🇸🇺"

(This is Ruby code, but you could do the same in any language. Update July 22, 2014: Except in Swift, where the opposite of capitalism is just capitalism. Because Swift is smart with strings.)

The lack of support for a full set of national flags in most emoji fonts kind of kills the joke, I know. It’s a shame.

I filed an enhancement request with Apple to add more flags to their emoji font. Feel free to do the same if you also want to see this.
