Indian traditions and conservatism. I **** to generalize but even if an Americanized Indian were to consider porn it would only be because there is no other way she can make money and her ****** is back home and doesn't have any idea of whats happening in her life . They will consider other options before porn.
Also most Indian-Americans are middle or upper middle class. They have other options that don't lead to porn. I know someone is going to try and note some exceptions, but that's more of the exception proving the rule.
From what we've read, Priya Rai comes from a middle class ******, but we don't know how stable it was.
