Obama deserved to lose—but the country doesn't deserve the consequences.

Asked on Monday to assess the significance of the coming Democratic defeat, Tim Kaine, the chairman of the Democratic National Committee, tried to portray this election as fairly typical. “Since Teddy Roosevelt,” Kaine told Gwen Ifill of the “PBS NewsHour,” “the average midterm is, you lose 28 House seats and lose four Senate seats if you’re the party in the White House.” Does losing over 60 House seats and as many as eight Senate seats simply make this a below average outcome, or did something much more serious and significant happen in yesterday’s election?

Republicans might say it’s the re-emergence of a conservative Republican majority, but that’s not really what happened. What this election suggests to me is that the United States may have finally lost its ability to adapt politically to the systemic crises that it has periodically faced. America emerged from the Civil War, the depression of the 1890s, World War I, and the Great Depression and World War II stronger than ever—with a more buoyant economy and greater international standing. A large part of the reason was the political system’s ability to provide the leadership the country needed. But what this election suggests to me is that this may no longer be the case.

This economic downturn structurally resembles the depressions of the 1890s and the 1930s rather than the cyclical recessions that have recurred since World War II. The American people, mired in debt, with one in six lacking full-time employment, are not spending; and businesses, uncertain of demand for their products, are not investing no matter how low interest rates fall. With the Fed virtually powerless, the only way to stimulate private demand and investment is through public spending. Obama tried to do this with his initial stimulus program, but it was watered down by tax cuts, and undermined by decreases in state spending. By this summer, its effect had dissipated.

The Republicans may not have a mandate to repeal health care, but they do have one to cut spending. Many voters have concluded that Obama’s stimulus program actually contributed to the rise in unemployment and that cutting public spending will speed a recovery. It’s complete nonsense, as the experience of the United States in 1937 or of Japan in the 1990s demonstrated, but it will guide Republican thinking in Congress, and prevent Obama and the Democrats from passing a new stimulus program. Republicans will accede to tax cuts, especially if they are skewed toward the wealthy, but tax cuts can be saved rather than spent. They won’t halt the slowdown. Which leads me to expect that the slowdown will continue—with disastrous results for the country.

And that’s only what one can expect over the next few years. Like the depressions of the 1890s and 1930s, this slowdown was also precipitated by the exhaustion of opportunities for economic growth. America’s challenge over the next decade will be to develop new industries that can produce goods and services that can be sold on the world market. The United States has a head start in biotechnology and computer technology, but as the Obama administration recognized, much of the new demand will focus on the development of renewable energy and green technology. As the Chinese, Japanese, and Europeans understand, these kinds of industries require government coordination and subsidies. But the new generation of Republicans rejects this kind of industrial policy. They even oppose Obama’s obviously successful auto bailout.
