Clearly, for good [the good of the world], and ill [the ill of the American middle], Empire is the future.
Check out Toynbee [also Spengler, et al.]. Inevitably the bulk of the middle class in Empires end up becoming what Toynbee calls internal proletariats.
This is obviously in the interest of some, but not of others. Still, while the overall process seems to have a significant degree of historical inevitability, the manner in which this all ends up being played out will be up to each of us.
Also note the rise of religious and spiritual interest around the world. Toynbee points out that last time this happened in the west [Roman Empire], much of the Mediterranean was divided between what he called zealots and their arch rivals, the hellenists. Obviouslly we have our Globalists and theo-cons today as well.
I myself take part in all this as an Evangelical Christian.
Ironic.
