Hathaway explains how our masters who "own" the economy (supported by our labor) use patriotism or nationalism which are rooted in patriarchy to control our minds so that we keep serving them.
Patriotism keeps us in the game. It's an instrument of control that's cultivated in us as children through emotional rituals designed to make us identify our nation with our family and with some higher power. These rituals create a bond of feeling linking God the Father, the Founding Fathers, and our own fathers into a patriarchal hierarchy that rewards us if we're obedient and punishes us if we're rebellious. It's a tool for keeping us in our place.
