About 82 percent of the new jobs created last year were temporary contracts, up from 70 percent only five years ago, not the kind of full-time work that opens the door to the French middle class. That keeps nearly an entire generation living precariously, no matter how hard people study or work.

Last year, France was ranked 28th out of the 60 most competitive economies in the world, according to the International Institute for Management Development in Lausanne, Switzerland. The United States was first. Even China, at 21, and Japan, at 24, outranked France. In the World Bank’s ranking of “ease of doing business,” France ranks 34th, compared with 7th for Britain and 20th for Germany.

In Amiens, in the north of France, Goodyear owns two tire factories. The work force at one has grudgingly accepted a change in work schedules, preserving its factory. The workers at the other have refused, and Goodyear is trying (not so easy in France) to shut it down, throwing more people out of work. Claude Dimoff, a former union leader at the more flexible plant, said: “I’m part of a generation that experienced the common program of the left. We had visions for the future, and different values, but all this is forgotten. The left has completely deviated from its promises.”

The country retains plenty of strengths. France is the world’s fifth-largest economy, with strong traditions in management, science and innovation. The gap between rich and poor is narrower in France than in most Western countries, although it is growing.

When the French work, they work hard; labor productivity, perhaps the single most important indicator of an economy’s potential, is still relatively high, if dropping. But with long holidays and the 35-hour week, the French work fewer hours than most competitors, putting an extra strain on corporations and the economy.

Large French companies compete globally; there are more French companies in the Fortune 500 than any other European country. But the bulk of their employees are abroad, and there are few of the midsize companies that are the backbone of Germany. Ninety percent of French companies have 10 or fewer employees and fear expansion because of extra tax burdens and strict labor regulations.

Even in France’s justly famous agricultural sector, the shrinking number of farmers has not been matched by a similar reduction in bureaucrats. Jacques Galaup, a farmer near Gaillac in the southwest, spoke with disdain of the number of hours he had to spend on paperwork — and estimated that there was probably one functionary now for every farmer.
