WASHINGTON

Germany has been a frequent cudgel in recent fights over the American economy. When Germany has grown faster than the United States, stimulus skeptics like to point across the Atlantic Ocean and say that austerity works. When it has grown more slowly, people who think the American stimulus made a big difference — including me — return the favor.

But the full story is more interesting than any caricature. In the last decade, Germany has succeeded in some important ways that the United States has not. The lessons aren’t simply liberal or conservative. They are both.

With our economy weakening once again — and with Chancellor Angela Merkel of Germany visiting the White House this week — now seems to be a good time to take a closer look.

The brief story is that, despite its reputation for austerity, Germany has been far more willing than the United States to use the power of government to help its economy. Yet it has also been more ruthless about cutting wasteful parts of government.
