How long do you suppose America can continue to exist as a relatively free nation with a government consisting of all the representation you can afford and an economy controlled by a few unregulated corporations with a populace of underpaid, unappreciated and increasingly unemployed citizens?
We are no longer the America envisioned by the founders. We aren't even the same United States we were after our civil war. No society in history has existed with all the same elements at play as we have in America in the 21st century. So we can't look back in order to predict our potential future. Perhaps three centuries is all the longer we can sustain this social experiment. Then again, maybe it's taken three centuries to reach maturity and stability.
Is America becoming a corporatocracy? Are we in danger of becoming a theocracy, a Christian version of Iran? Will our current social, political and economic issues drive us back into a more responsible form of a republic? What do you see in America's future?
