I say this genuinely. It's not clear what you are trying to say.

I'll lay my cards on the table. It is true that casteism conducts to the Indian disapora abroad with no degradation in fervor. Upper caste Indian disapora enjoy a socioeconomic advantage in a country like the US.

But with Kamala there is enough cross cultural exchange to break the casteism angle. I am operating on vibes and limited knowledge. For example her mother pursued her marriage without her parents butting in too much. Kamala herself seems to not acknowledge her Indian heritage (you mocked this word before but I can't think for a better alternative) much, let alone her Brahmin heritage. So in my view she benefits from the socioeconomic status from her parents, but not much of that from being enmeshed in a upper caste disapora community.

There is already enough incentive in the US society to generate BIPOC ghouls. It's not necessary to factor in her Brahmin heritage to justify her path post-hoc.
