ROBERT SAMUELSON: DON’T EXPECT GERMANY TO SAVE EUROPE. “The dark truth may be that even a willing Germany can’t rescue Europe. . . . To Germans, other European countries must now adjust to new, if unpleasant, realities.

Economic growth is too low, populations are aging and demands on pension and health-care systems are too high.”
