You may have already done this; to break down what one means by "we" / "us" / "american" that unless he is part of the bourgoisie (at which point one may want to invest time elsewhere to overthrow the dictatorship) that there are material differences between himself and those who dictate the policies of empire?
There's only so much one can do though if one is in the imperial core especially if one's father is reasonably well off. Unfortunately there are material benefits of the empire for the imperial core labour aristocrats and petite-bourgoise even if they are crumbs.
Finding common grounds or points of agreement is often the path to extrapolate towards reconciliation and exploration of meaningful enlightenment without capitulation.
