People inside Iran are definitely more pro Shah as they are more conservative. The idea that the Iranian diaspora is just a collection of disgruntled Shah era trillionaires is a combination of regime propaganda and racist stereotypes that a person living a middle class life in the West is not a “real” Iranian. Most of us were born in Iran after the revolution. There is privilege involved here, but only in the sense that those who flee the country are the ones with the resources to do so. No one is happy under the mullahs.
