Were there no European union there would be no Greek crisis beyond Greece, Greece would have retained its currency and paid its price for budget problems in the value of its currency.
But the stitching together of so many diverse countries and cultures into one unit, with one currency, has presented far more problems than it has solved and, worse, has removed national freedom, sovereignty, and the necessary freedom of tariff-based re-balancing mechanisms. As a result, we now have synchronized pain and ruin serving to give the banksters more opportunities to gain evermore resources and power over our lives with their out-of-thin-air private money machines.
Worst of all is exactly this private central bank contagion, in which nations have given up their rights to create their own money and credit, and without interest if they see fit. The world-wide sovereign debt problem is essentially a private central bank, debt-money, problem. It's the interest, stupid. Its the inevitable Kondratieff wave of debt-money.
Indeed, it is the unnecessary and predatory interest on private debt that countries and municipalities alike are forced to pay to parasitic bankers and Fed-owning bond dealers, instead of creating their own money and credit, and keeping their collected taxpayer funds in state and national banks.
The banksters then have us in their straightjacket and are attempting to use this crisis of their own making to mount a global coup of "global governance" in which all nations give up their money and credit freedom and enter the banker hell roach motel... then try to get out?
Interdependency is not stopping wars, riots, revolutions or currency trade wars. It's merely removing freedom, democracy, and domestic re-balancing mechanisms. It is also producing a dismal sameness around the world and ruining the beauty and freedom of cultural diversity.
