Now that is a loaded word. It is often invoked by the "Internationalist" as a derogatory term.
Way back in the 1970's I read a book entitled: The Economic Bases of Peace by Ernest Minor Patterson (Not: The Economic Basis of Peace) It dealt extensively with Autarchy, Internationalism, Intranationalism, Regionalism, A World Economy, The book was first published in 1939, my reprint was done around 1971.
Went to my library tonight and intend over the next few days to revisit it. Have a couple of other books from the 1929-1939 period that I may look at again. In light of the Global Economic Mess.
None of these structures are without problems. Certainly "Globalism" (and it's blind leap of faith) are not without dangers. In my opinion, Globalism is the semi-structure with the most potential for evil. For that reason I have contempt for those who zealously persue that as a final solution.
Old Chinese proverb: "Today's problems were often yesterdays solutions."
Accurate.
Our own financial problems can be traced back to "progressive" reforms. It's a curious thing that somebody convinced the "bright" folks in power once to create a federal reserve. A "bank" where the government goes to borrow money to deploy into our system. The federal reserve first invents the money and then charges the US government interest for its services. The US government could just as easily invent the exact same money by itself without the services of the federal reserve, but avoid entirely the interest costs associated with the transaction.
But why do that when accumulating debt is so much fun?
