You can sum up much of 20th century history by saying that in the 1930s Americans decided that markets didn't work and government did, and that in the 1970s Americans decided that government didn't work and markets did.

The protracted and painful experiences of those decades changed basic public attitudes on the balance between government and markets, between regulation and enterprise, between government aid programs and self-reliance. The breadlines and depression of the 1930s moved Americans in one direction; the gas lines and stagflation of the 1970s moved them in the other.

Which raises the question of whether the financial ructions of 2007-08 (09?) will move them back again. One reason to believe this is possible is the passage of time. Americans in the 1980s and 1990s were ready to accept deregulation and tax cuts and welfare reform because so few of them had personal memories of the 1930s.

In 1992, Bill Clinton ran as a different kind of Democrat because so many voters then had personal memories of the 1970s. Today, fewer do. Half the voters did not reach adulthood until the 1980s. They never sat behind the steering wheel in a gas line or paid monthly bills as inflation was skyrocketing. It's plausible that they may be more open to big government programs than their elders.

Barack Obama and other Democrats have used the financial crisis to spin a narrative. The problem, they say, is deregulation and greed. This is not strictly speaking accurate. Obama and the Democrats opposed tighter regulation of the mortgage giants Fannie Mae and Freddie Mac, and John McCain supported it. Unregulated firms like hedge funds have done well, while heavily regulated banks have had troubles.

But the narrative will be advanced by the Obama-loving media ... and by the passage of a giant financial bailout — er, rescue package. The likelihood, as this is written, is that Obama will be elected president and the Democrats will expand their congressional majorities. Possibly even to the 60 votes they need to effectively control the Senate.

In that case, Democrats might be able to move toward nationalized health care finance. Their card-check bill will promote unionization and do to much of the private sector what union contracts have done to the Detroit Three automakers. Higher taxes and overregulation could reduce economic vitality and creativity. Comparable worth laws could have bureaucrats setting private sector salaries. America could move some distance to becoming another France.

Those seeking that outcome would do well to study some history. Some New Deal-Great Society programs have mostly worked well over the long term: bank deposit insurance, securities market regulation. Some worked well for many years but are on the road to something like financial collapse: Social Security, Medicare. But some had adverse economic effects and proved unpopular: high taxes on high earners, industrial unionization.

The economy in the 1930s suffered from what Amity Shlaes in "The Forgotten Man" calls a "capital strike," with unemployment stuck over 10 percent. Take a look at the polls in the 1940 election. If voters had decided on domestic issues, the Democrats probably would have lost. Franklin Roosevelt won because Adolf Hitler, with his then-ally Joseph Stalin, had conquered most of Europe and was threatening Britain and the United States. Roosevelt's experience and his steady hand on foreign policy won him his third term.

The war that followed produced huge economic growth and sharp increases in income equality — the biggest such movement in American history. But the war policies — government taking up nearly half of gross domestic product, the mobilization of the equivalent of 37 million in the military — are not replicable under any circumstances foreseeable today.

Postwar America continued to grow, with help from the John Kennedy tax cuts, declining unionization and (I would argue) the civil rights acts. But eventually, in the 1970s, regulation designed to freeze a static economy in place and macroeconomic policies complacent about the danger of inflation (the big problem in the 1930s was deflation) produced the gas lines and stagflation voters rebelled against. Policies inspired by the inflection point of the 1930s led to a different inflection point in the 1970s.

Are we looking at another inflection point today? Maybe so. Reviewing the long course of history, I think it's obvious that market capitalism, together with the rule of law, hard currency and regulations that ensure transparency and accountability, has produced bounteous growth and the resources to address problems that require government action, like defending the nation and protecting the environment. But voters tend to consider only the history they know. They might do well to look back a little further.
