Is the world economic crises rooted in socialist policies of developing countries?

I agree. It isn't so much that when government undertakes to tweak the economy that their economic models are flawed as much as the act of tweaking the economy in itself simply wastes vast amounts of tax dollars without effect. The main drivers of economic activity will simply counteract whatever the government does, initiating a high-gain feedback loop in which now, the stimiulus package has become ruinously expensive and there is no prospect for paying for it, much less the stimulus having the desired effect. The best thing the government could do for the economy is what Clinton and the Republican Congress of the mid-late 1990's did - stop deficit spending and take its mitts off. Except this time, forget about using the Fed to generate an artificial money supply by cutting the prime rate to nothing.
