ACROSS WESTERN EUROPE, the “lifestyle superpower,” the assumptions and gains of a lifetime are suddenly in doubt. The deficit crisis that threatens the euro has also undermined the sustainability of the European standard of social welfare, built by left-leaning governments since the end of World War II.

Europeans have boasted about their social model, with its generous vacations and early retirements, its national health care systems and extensive welfare benefits, contrasting it with the comparative harshness of American capitalism.

Europeans have benefited from low military spending, protected by NATO and the American nuclear umbrella. They have also translated higher taxes into a cradle-to-grave safety net. “The Europe that protects” is a slogan of the European Union.

But all over Europe governments with big budgets, falling tax revenues and aging populations are experiencing rising deficits, with more bad news ahead.

With low growth, low birthrates and longer life expectancies, Europe can no longer afford its comfortable lifestyle, at least not without a period of austerity and significant changes. The countries are trying to reassure investors by cutting salaries, raising legal retirement ages, increasing work hours and reducing health benefits and pensions.

“We’re now in rescue mode,” said Carl Bildt, Sweden’s foreign minister. “But we need to transition to the reform mode very soon. The ‘reform deficit’ is the real problem,” he said, pointing to the need for structural change.

The reaction so far to government efforts to cut spending has been pessimism and anger, with an understanding that the current system is unsustainable.

In Athens, Aris Iordanidis, 25, an economics graduate working in a bookstore, resents paying high taxes to finance Greece’s bloated state sector and its employees. “They sit there for years drinking coffee and chatting on the telephone and then retire at 50 with nice fat pensions,” he said. “As for us, the way things are going we’ll have to work until we’re 70.”

In Rome, Aldo Cimaglia is 52 and teaches photography, and he is deeply pessimistic about his pension. “It’s going to go belly-up because no one will be around to fill the pension coffers,” he said. “It’s not just me; this country has no future.”

Changes have now become urgent. Europe’s population is aging quickly as birthrates decline. Unemployment has risen as traditional industries have shifted to Asia. And the region lacks competitiveness in world markets.

According to the European Commission, by 2050 the percentage of Europeans older than 65 will nearly double. In the 1950s there were seven workers for every retiree in advanced economies. By 2050, the ratio in the European Union will drop to 1.3 to 1.

“The easy days are over for countries like Greece, Portugal and Spain, but for us, too,” said Laurent Cohen-Tanugi, a French lawyer who did a study of Europe in the global economy for the French government. “A lot of Europeans would not like the issue cast in these terms, but that is the storm we’re facing. We can no longer afford the old social model, and there is a real need for structural reform.”

In Paris, Malka Braniste, 88, lives on the pension of her deceased husband. “I’m worried for the next generations,” she said at lunch with her daughter-inlaw, Dominique Alcan, 49. “People who don’t put money aside won’t get anything.”

Ms. Alcan expects to have to work longer as a traveling saleswoman. “But I’m afraid I’ll never reach the same level of comfort,” she said. “I won’t be able to do my job at 63; being a saleswoman requires a lot of energy.”

Figures show the severity of the problem. Gross public social expenditures in the European Union increased from 16 percent of gross domestic product in 1980 to 21 percent in 2005, compared with 15.9 percent in the United States. In France, the figure now is 31 percent, the highest in Europe, with state pensions making up more than 44 percent of the total and health care, 30 percent.

The challenge is particularly daunting in France, which has done less to reduce the state’s obligations than some of its neighbors. In Sweden and Switzerland, 7 of 10 people work past 50. In France, only half do. The legal retirement age in France is 60, while Germany recently raised it to 67 for those born after 1963.

With the retirement of the baby boomers, the number of pensioners will rise 47 percent in France between now and 2050, while the number under 60 will remain stagnant.

The problems are more acute in the “new democracies” of the euro zone- Greece, Portugal and Spain - that embraced European democratic ideals and that Europe embraced for political reasons in the postwar era, perhaps before their economies were ready. They have built lavish state systems on the back of the euro, but now must change.

All three need to bolster their competitiveness and growth, mostly by changing deeply inflexible employment rules, which can make it prohibitively expensive to hire or fire staff members, keeping unemployment high.

In Athens, Mr. Iordanidis, who makes 800 euros a month in a bookstore, said he saw one possible upside. “It could be a chance to overhaul the whole rancid system,” he said, “and create a state that actually works.”
