If you feel like you can't effect change where you are (a fair conclusion), I would suggest at the very least looking into moving to another country which is more representative of your values.

Yes, it seems like giving up. But then over time the more smart, educated, likely wealthy people leave the US and take residence somewhere less objectionable, the less economically competitive the US will be. Eventually it will decline.

At the very least, you'll know that you weren't one of the people contributing to sustaining this system. It might seem like a drop in the ocean, but, as the conclusion of Cloud Atlas puts it, what is the ocean but a multitude of drops?
