They've gotten better at culture, as in, trying to understand different cultures and branching out their own interests and experiences beyond what is American.

Are you asking me how to quantify culture? You could go buy services like what WGSN offers, or you can just not be a socially inept corporate econometrics data clown and leave your house once in a while, interact with young people, and use your eyes.

"Culture" in American vernacular essentially means non-anglo food (90%) plus festivals and other folk things (10%). I know, it's weird.

It doesn't count as American culture until the guy who is pushing it clears a million dollars.
