"I think the rich will eventually have to cave in too, because the economic situation around the world is not gonna tolerate the United States being on top forever"

She implies that the present financial scenario around the world is unsustainable which the United States can not stay on the top permanently. This implies that the rich will have to accept a shift in the balance of power and wealth, which the present system of inequality will not be able to continue forever.
