... From the financial sectors vantage point, the solution to the Eurozone crisis is to reverse the aims of the Progressive Era a century ago what in 1936 John Maynard Keynes hopefully termed euthanasia of the rentier. The idea was to subordinate the banking system to serve the economy rather than the other way around. Instead, finance has become the new mode of warfare less ostensibly bloody, but with the same objectives as the Viking invasions over a thousand years ago, and Europes subsequent colonial conquests: appropriation of land and natural resources, infrastructure and whatever other assets can provide a revenue stream. It was to capitalize and estimate such values, for instance, that William the Conqueror compiled the Domesday Book after 1066, a model of ECB and IMF-style calculations today.
This appropriation of the economic surplus to pay bankers is turning the traditional values of most Europeans upside down. Imposition of economic austerity, dismantling social spending, sell-offs of public assets, de-unionization of labor, falling wage levels, scaled-back pension plans and health care in countries subject to democratic rules requires convincing voters that there is no alternative. It is claimed that without a profitable banking sector (no matter how predatory) the economy will break down as bank losses on bad loans and gambles pull down the payments system. No regulatory agencies can help, no better tax policy, nothing except to turn over control to lobbyists to save banks from losing the financial claims they have built up.
What banks want is for the economic surplus to be paid out as interest, not used for rising living standards, public social spending or even for new capital investment. Research and development takes too long. Finance lives in the short run...

... And the proximate "cause" of the crisis is the same. International financial speculators sold credit to those they must have known would evenytually have trouble paying... exactly like (and done by some of the same people) as the original US junk-mortgage scam (the 'trigger') - plus the mountain of leveraged derivatives piled up on top of that - calculating that eventually it would be 'taxpayers', the 99%, that would be made to suffer and pay.
