The Austrians are liquidationists, who believe that austerity and human misery are the cure. You first have to recognize the disease: the initial "high" that the credit bubble induced. While others are figuring out whether to shoot up between the toes or in the arm, the Austrians explain the obvious: cold turkey withdrawal is the only cure for heroin addiction. The so-called "cures" recommended by others seek to prolong the addiction.
New investment will create new jobs, and fill excess capacity. New jobs mean more income, which means the cycle of new investment, new jobs, and new demand will continue. That's not addiction, that's the way the real economy works. One of the many mistakes the Austrians make is to look at the growth of debt without comparing it to the growth of revenue, or adjusting it for interest rates. They position themselves correctly as anti-Keynesians, while making the huge mistake by denying that supply-siders even exist.
The Austrians seek to prolong human misery, and they think the Great Depression is the best thing that ever happened to our economy.
