Because of Greece's horrible economy, this link has obvious rhetorical appeal.

But there's another nation that may be a more accurate "role model" of America's future. This other country, like the United States, is big, relatively rich, and has its own currency.

For these and other reasons, in an article for The Hill, I suggest that Japan is the nation that may offer the most relevant warning signs. I explain first that Japan shows the failure of Keynesian economics.

…ever since a property bubble burst in the late 1980s, Japan's economy has been in the doldrums, and its politicians deserve much of the blame. They've engaged in repeated binges of so-called Keynesian stimulus. But running up the national credit card hasn't worked any better in Japan than it did for President Barack Obama. Instead of economic rejuvenation, Japan is now saddled with record levels of debt.

In other words, Japan already is a basket case and may be the next Greece. And all this foolish policy has been cheered on by the IMF.
