If you only read one opinion column this year, this is the one you should read. And then you’ll never have to listen to people like Hannes Holmsteinn Gissurarson ever again.
It is long but it should be required reading.
So here’s what I think economists have to do. First, they have to face up to the inconvenient reality that financial markets fall far short of perfection, that they are subject to extraordinary delusions and the madness of crowds. Second, they have to admit — and this will be very hard for the people who giggled and whispered over Keynes — that Keynesian economics remains the best framework we have for making sense of recessions and depressions. Third, they’ll have to do their best to incorporate the realities of finance into macroeconomics.
Many economists will find these changes deeply disturbing. It will be a long time, if ever, before the new, more realistic approaches to finance and macroeconomics offer the same kind of clarity, completeness and sheer beauty that characterizes the full neoclassical approach. To some economists that will be a reason to cling to neoclassicism, despite its utter failure to make sense of the greatest economic crisis in three generations. This seems, however, like a good time to recall the words of H. L. Mencken: “There is always an easy solution to every human problem — neat, plausible and wrong.”
When it comes to the all-too-human problem of recessions and depressions, economists need to abandon the neat but wrong solution of assuming that everyone is rational and markets work perfectly. The vision that emerges as the profession rethinks its foundations may not be all that clear; it certainly won’t be neat; but we can hope that it will have the virtue of being at least partly right.

One economist got it right, but no one paid any attention to him.
In the 1960s, Minsky predicted exactly what would happen to the economy in the 2000s.
http://www.informationclearinghouse.info/article23493.htm
Minsky “believed in capitalism, but also believed it had almost a genetic weakness. Modern finance, he argued, was far from the stabilizing force that mainstream economics portrayed: rather, it was a system that created the illusion of stability while simultaneously creating the conditions for an inevitable and dramatic collapse. In other words, the one person who foresaw the crisis also believed that our whole financial system contains the seeds of its own destruction. “Instability,” he wrote, “is an inherent and inescapable flaw of capitalism.”
Minsky formulated an intriguing theory: not only was capitalism prone to collapse, he argued, it was precisely its periods of economic stability that would set the stage for monumental crises.
Minsky called his idea the “Financial Instability Hypothesis.” In the wake of a depression, he noted, financial institutions are extraordinarily conservative, as are businesses. With the borrowers and the lenders who fuel the economy all steering clear of high-risk deals, things go smoothly: loans are almost always paid on time, businesses generally succeed, and everyone does well. That success, however, inevitably encourages borrowers and lenders to take on more risk in the reasonable hope of making more money. As Minsky observed, “Success breeds a disregard of the possibility of failure.”
As people forget that failure is a possibility, a “euphoric economy” eventually develops, fueled by the rise of far riskier borrowers – what he called speculative borrowers, those whose income would cover interest payments but not the principal; and those he called “Ponzi borrowers,” those whose income could cover neither, and could only pay their bills by borrowing still further. As these latter categories grew, the overall economy would shift from a conservative but profitable environment to a much more freewheeling system dominated by players whose survival depended not on sound business plans, but on borrowed money and freely available credit.
Once that kind of economy had developed, any panic could wreck the market. The failure of a single firm, for example, or the revelation of a staggering fraud could trigger fear and a sudden, economy-wide attempt to shed debt. This watershed moment – what was later dubbed the “Minsky moment” – would create an environment deeply inhospitable to all borrowers. The speculators and Ponzi borrowers would collapse first, as they lost access to the credit they needed to survive. Even the more stable players might find themselves unable to pay their debt without selling off assets; their forced sales would send asset prices spiraling downward, and inevitably, the entire rickety financial edifice would start to collapse. Businesses would falter, and the crisis would spill over to the “real” economy that depended on the now-collapsing financial system.
DOES THIS SCENARIO SOUND FAMILIAR?

Blubber: Unfortunately I cannot promise you that
Vilhjalm A: Yes, that scenario sounds very familiar, we should be more careful with “freshwater” economists in the future. Unfortunatly they make so much goddamned noise.
