America has always been a ‘divided’ country. When formed our population was freed from tyranny, the tyranny that forced people to act within the bounds established by the privileged few. Every person was now free to act in their own self interest. So, a population divided in their wants and needs and free enough to act in a way that satisfied these needs is the nation that our founders envisioned.
As the little meme above demonstrates, freedom and capitalism, carried to the extreme, can result in the resurrection of the same tyranny it was so successful at defeating
My personal view is that Nationalism (the terribly feared word/concept) is the only potion that can rid us from the cycle of tyranny. All Americans, rich and poor, were they to act in the best interest of the country (as conceived by its founders) while living their dreams, raising their children, and worshiping their God, would end this sickness in the nation.
