A thoughtful, fact-filled essay on the social welfare stresses in Europe:

PARIS — 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….

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….

“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.”…

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.
