Go read the latest Krugman OP/ED, he is at the top of his game:
Mr. Bernanke cited “the depth and sophistication of the country’s financial markets (which, among other things, have allowed households easy access to housing wealth).” Depth, yes. But sophistication? Well, you could say that American bankers, empowered by a quarter-century of deregulatory zeal, led the world in finding sophisticated ways to enrich themselves by hiding risk and fooling investors.
And wide-open, loosely regulated financial systems characterized many of the other recipients of large capital inflows. This may explain the almost eerie correlation between conservative praise two or three years ago and economic disaster today. “Reforms have made Iceland a Nordic tiger,” declared a paper from the Cato Institute. “How Ireland Became the Celtic Tiger” was the title of one Heritage Foundation article; “The Estonian Economic Miracle” was the title of another. All three nations are in deep crisis now.
(emphasis mine)
Keynes was right when he warned on how unrestricted torrents of capital could destabilize destroy an economy.
