The members of the Obama administration have many fine talents, but making adept historical analogies may not be among them.

When the administration came to office in the depths of the financial crisis, many of its leading figures concluded that the moment was analogous to the Great Depression. They read books about the New Deal and sought to learn from FDR.

But in the 1930s, people genuinely looked to government to ease their fears and restore their confidence. Today, Americans are more likely to fear government than be reassured by it.

According to a Gallup survey, 64 percent of Americans polled said they believed that big government is the biggest threat to the country. Only 26 percent believed that big business is the biggest threat. As a result, the public has reacted to Obama's activism with fear and anxiety. The Democrats lost 63 House seats in the 2010 elections.

Members of the administration have now dropped the New Deal parallels. But they have started making analogies between this era and the progressive era around the turn of the 20th century.

Again, there are superficial similarities. Then, as now, we are seeing great concentrations of wealth, especially at the top. Then, as now, the professional class of lawyers, teachers and journalists seems to feel as if it has the upper hand in its status war against the business class of executives and financiers.

But these superficial similarities are outweighed by vast differences.

First, the underlying economic situations are very different. A century ago, the U.S. economy was a vibrant jobs machine. Industrialization was volatile and cruel, but it produced millions of new jobs, sucking labor in from the countryside and from overseas.

Today's economy is not a jobs machine and lacks that bursting vibrancy. The rate of new business startups was declining even before the 2008 financial crisis. Companies are finding that they can get by with fewer workers. As President Barack Obama has observed, factories that used to employ 1,000 workers can now be even more productive with fewer than 100.

Moreover, the information economy widens inequality for deep and varied reasons that were unknown a century ago. Inequality is growing in nearly every developed country. According to a report from the Organization for Economic Cooperation and Development, over the past 30 years, inequality in Sweden, Germany, Israel, Finland and New Zealand has grown as fast or faster than inequality in the United States, even though these countries have very different welfare systems.

In the progressive era, the economy was in its adolescence and the task was to control it. Today the economy is middle-aged; the task is to rejuvenate it.

Second, the governmental challenge is very different today than it was in the progressive era. Back then, government was small and there were few worker safety regulations. The problem was a lack of institutions. Today, government is large, and there is a thicket of regulations, torts and legal encumbrances. The problem is not a lack of institutions; it's a lack of institutional effectiveness.

The United States spends far more on education than any other nation, with paltry results. It spends far more on health care, again with paltry results. It spends so much on poverty programs that if we just took that money and handed poor people checks, we would virtually eliminate poverty overnight. In the progressive era, the task was to build programs; today the task is to reform existing ones.

Third, the moral culture of the nation is very different. The progressive era still had a Victorian culture, with its rectitude and restrictions. Back then, there was a moral horror at the thought of debt. No matter how bad the economic problems became, progressive-era politicians did not impose huge debt burdens on their children. That ethos is clearly gone.

In the progressive era, there was an understanding that men who impregnated women should marry them. It didn't always work in practice, but that was the strong social norm. Today, that norm has dissolved. Forty percent of American children are born out of wedlock. This sentences the United States to another generation of widening inequality and slower human capital development.

One hundred years ago, we had libertarian economics but conservative values. Today we have oligarchic economics and libertarian moral values – a bad combination.

In sum, in the progressive era, the country was young and vibrant. The job was to impose economic order. Today, the country is middle-aged but self-indulgent. Bad habits have accumulated. Interest groups have emerged to protect the status quo. The job is to restore old disciplines, strip away decaying structures and reform the welfare state. The country needs a productive midlife crisis.

The progressive era is not a model; it is a foil. It provides a contrast and shows us what we really need to do.
