An economic downturn in 1920-21 sent unemployment up to 12 percent. President Warren Harding did nothing, except for cutting government spending. The economy quickly rebounded on its own.
In 1987, when the stock market declined more in one day than it had in any day in 1929, Ronald Reagan did nothing. There were outcries and outrage in the media. But Reagan still did nothing.
That downturn not only rebounded, it was followed by 20 years of economic growth, marked by low inflation and low unemployment.
The Obama administration's policies are very much like the policies of the Roosevelt administration during the 1930s. FDR not only smothered business with an unending stream of new regulations, he spent unprecedented sums of money, running up record deficits, despite raising taxes on high income earners to levels that confiscated well over half their earnings.
Like Obama today, FDR blamed the country's economic problems on his predecessor, making Hoover a pariah. Yet, 6 years after Hoover was gone, and nearly a decade after the stock market crash, unemployment hit 20 percent again in the spring of 1939.
Doing nothing may have a better track record in the economy but government intervention has a better political record in getting presidents re-elected.
People who say that Barack Obama cannot be re-elected with unemployment at its current level should take note that Franklin D. Roosevelt was elected a record four times, despite two consecutive terms in which unemployment was never as low as it is today.
Economic reality is one thing. But political impressions are something very different -- and all too often it is the political impressions which determine the fate of an administration and the fate of a nation.
