What prospect is there for national forms of economic prudence when we're drowning in a giant global liquid pool of finance capital of which only a tiny fraction derives from the production of real goods and services? 
Doug Nolan this week:
"....Think in terms of the surge of inflation that forced thoughtful policymakers in economies such as Australia, New Zealand and elsewhere to significantly tighten monetary policy. Rising rates, however, only enticed more disruptive speculative finance flowing loosely from (low-yielding) Credit systems including the U.S., Japan, and Switzerland. Speculation could have been as simple as shorting a low-yielding security anyplace to finance a higher-returning asset anywhere. Or, why not structure a complex leveraged derivative transaction that, say, borrowed in a cheap currency (i.e. yen or swissy), played the upside of rising emerging equities markets, and at the same time had triggers to hedge underlying currency and/or market exposure. And the counterparty exposure for a lot hedges could be wrapped up in collateralized debt obligations (CDOs). And the more loose global finance inflated the world, the more the leveraged speculating community inundated “commodity” economies such as Australia, Canada, Brazil, South Africa and Russia. Of course, speculative inflows ignited domestic asset market and Credit systems, in the process fostering dangerous Bubbles...." 
And some comments from Naked Capitalism in the last few days:
"a lot of the depression we're all going to get now is because Japan expanded its money supply but held interest rates low for those 15 years in a attempt to duck recession. With low domestic rates, there was no place for the money domestically so it went abroad via the carry trade and blew bubbles all over the planet...
"...I never saw [Japan's] zero [interest rate] policy as anything but a long-term disaster; one can't get any kind of velocity or domestic economy at long term zero or neg rates, it's madness. The destabilizing impact of dollar debt expansion has mattered far more in this global bubble than the cheap yen, but the irrationality of the Japanese yen bloat backstoped their standard of living for fifteen years at the coast of their _next_ fifteen years, yes, and they have their share of irresponsibility in the global bust. Why didn't Japan, really, take a knock and move on? Hard times would have socially knocked their crony capitalist one-party regime out of authority for something rather more leftish. This wasn't so much about saving the banks but about saving the 'Power System.' Which is why US public authorities are trying the same bad approach: it's all about saving the One Party Capitalist system...
