Barry Eichengreen, an expert on the Great Depression, and Kevin O'Rourke, take issue with the notion that the current downturn is less severe than the Great Depression. While the slump in the US is not as bad, that mis-states the global picture.
Note that many economists expect the US to suffer less than the big exporters, namely China, Germany, Japan. The reason is that the economic adjustment required of surplus nations is greater than that of debtors. Similarly, in the Great Depression, the US, then a major exporter, was harder hit than the overconsuming importers such as Britain, who defaulted on their debts.
The one bit of cheer is that this time around, government action is more aggressive, but it remains to be seen whether it is sufficient.
