Could the present slump really last for a decade or more? The truth is we don’t know and can’t know. The future course of capitalism is largely unpredictable. Economic forecasting is no more reliable than an astrological horoscope. All we can say with certainty is that it is an irrational system.
A number of quite distinct and separate things need to happen before a slump can run its course. Firstly, capital has to be wiped out if excess productive capacity is to be tackled with devalued capital being bought cheaply by those enterprises in the best position to survive the slump. Secondly, de-stocking needs to take place, with overproduced commodities bought up cheaply or written off entirely. Investment will not resume if overproduction still exists. Thirdly, after this has occurred there needs to be an increase in the rate of industrial profit helped both by real wage cuts and falling interest rates (which tail off naturally as the demand for more money capital eases off in the slump). This will help renew investment and increase accumulation. Also, if recovery is to be sustained, a large proportion of the debt built up during the boom years will need to be liquidated, if it is not to act as a drag on future accumulation. Through these mechanisms a slump helps build the conditions for future growth, ridding capitalism of inefficient units of production. When these processes have run their course, accumulation and growth can begin once more with capitalism again creating a boom situation, which will be inevitably followed by a crisis and slump. This has been the history of capitalism ever since it first developed. Far from being an aberration, this cycle of misery is the natural cycle of capitalism.
