I don't think the analogy is quite correct though. At least based only on the movie impressions of ghettos I've seen, I feel it's sort of an interesting ironic antonym of cultural personalities.
If many of the people in your ghetto had the same cultural identity as many of our poor people over here, you'd see a more unified poverty like the one I imagine exists in the Filipino groups in San Francisco. (I haven't been outside of my country except for HK and so I'm only guessing.)
In reverse, if we have more of a ghetto culture, it won't necessarily mean we will lift up ourselves better but certainly we'd be a lot more angrier and violent at the poverty level that in ways may further hurt our very unstable lifestyle but will be better breeding grounds for the type of entrepreneurs that mimic the US lifestyle.
People also don't seem to have the same level of confidence in themselves here. Kind of hard for me to understand as I am from what is considered the "greatest" country in the world. Hard to imagine what its like for someone growing up in the 3rd world. The only analogy I can draw is perhaps someone coming from a rich family vs someone coming from the ghetto.
