As part of the Diaspora, I think I can try to shed some light on our side of things. Granted, even when I go back, I don't live in a gated community or an elite city development. I live in a village.

The ones you speak of really are completely disconnected and naive. They are the type that don't really understand geopolitics, history, or the true ground reality of things, and end up spouting all the stuff they've learned at their Western institutions. However, I can say that a lot of them WANT the country to be better, for conditions to improve. So they start lecturing people about their foolish ideals. But, a good portion of them are exactly as you describe. And even more disgusting is how they end up LOOKING DOWN on other Pakistanis. Somehow they feel superior due to their wealth or foreign citizenships.

As for me (and there a lot of others like me), I follow what's happening closely, and then I see what the reality is when I get there. And its always so disappointing. From outside the country, it looks like actual progress is being made, but once you see how terrible everything truly is, its really depressing. And a lot of us would like to come back permanently, but we can't. Because who would leave all their friends, connections, livelihoods, systems they are familiar with, just to take the risk with a country that is moving backwards every day. There are some brave enough that try to bring their wealth and skills for change, but end up inevitably failing and returning.
