Travel to Europe these days and you will have to make sure that the transportation systems are not being gripped by strikes. Less productivity, slower growth, and higher unemployment are emblems of Europe's malaise. Morale in continental Western Europe is at record lows. While left-leaning Europeans imagine that they've invented a more humane approach to capitalism, the sustainability of their high-tax, high-regulation, high-welfare economy is in question. Can Europe restore its competitiveness without strong medicine? Have European elites failed to educate their publics about the choices they face? Can Europe gain the international clout it craves without ditching socialism? Sabine Herold, spokeswoman for Liberte, j'ecris ton nom (Liberty, I Write Your Name) is the French activist who led a student revolt against strikes provoked by French trade unions. She debated Charles Kupchan, associate professor of international affairs at Georgetown University and author of "The End of the American Era." Radek Sikorski, executive director of NAI, moderated the debate.
