So for now, the world must hope that Americans continue gorging on foreign imports.

When I think of those Germans gorging themselves on French wines, it makes me quite furious.

'All you can have' vacation packages, 'supersize me's, cater to the same instinct of hoarding and gorging.

Likewise, economists have long noted that for countries gorging on capital inflows, there is a big difference between debt instruments and equity like investments, including both stocks and foreign direct investment.
