In fact, it will only worsen their condition. Production takes place in stages, with consumption being the lowest stage of production. Concentrating spending at this stage directs resources from the higher stages, which in turn will raise their costs of production and thus aggravate their financial situation, even endangering companies that would have other wise survived the crisis. Eventually the government would be forced to apply the monetary breaks, sending the economy into another depression. The lesson from the American 1920 crisis is that Governments should do nothing.
Depressions are actually recovery processes during which maladjustments are purged from the economy.
They are, in a sense, withdrawal symptoms. Trying to cure the business cycle with monetary injections is like trying to cure a heroin addict by pumping more heroin into him. Therefore the Japanese government should ignore the Keynesians, cut taxes and allow the market to liquidate the malinvestments. Inflation is the disease, not the cure. I am using the Austrian economic school's theory of depressions to explain what happened to Japan in the 1920s and what is also happening in the present.
