Top Gun,
Well that's a nice LONG quote but no where in it did it include any stats showing that this downturn is worse than those that have come before since the Great Depression. The reason is obvious - if any stats were provided they would easily be proven to be wrong or not significant. There have been about 12 recessions since the great depression and 4 of them have been worse than this one by objective measures; measure like GDP and employment.
What your article did do was to highlight a quote that some economists have CALLED this the most serious crisis since the GD. Of course there are others who have not called it that and the credibility of economists is dubious when 1) they work for the organization that is paid by the government, 2) they stand to gain by calling it a great crisis, and 3) they have not provided any objective reason to believe them.
The nice thing about wiki is that they provide a list of sources for what they say and even links.
That statement from "leading economists" goes back to a Reuters article in which a sum total of 3 economists are quoted and no stats are given. The three economists work for CERA (which is owned by IHS), IHS, and the IMF. All three bodies get paid by the US government to say what they want to be said.
Here is a statement about the IMF (international monetary fund):
"Using panel data for 155 countries over the period 1999-2005 we empirically investigate the politics involved in IMF economic forecasts. We find a systematic bias in growth and inflation forecasts. Our results indicate that countries voting in line with the US in the UN General Assembly receive better inflation forecasts. As the US is the [international monetary] Fund’s major shareholder, this result supports the hypothesis that the Fund’s forecasts are not purely based on economic considerations. The “defensive lending” hypothesis is, to some extent, confirmed by the results as inflation forecasts are systematically biased downwards for countries more exposed to the IMF."

But if you still think this is a worse recession then just provide on statistic that is significant to support that point of view.
According to the NBER (another political government entity) aside from the GDP there are four major indicators of recession: Slower consumer spending, inverted yield curve, rising unemployment, and inflationary pressure.

Those do not show that we are in a worse recession since the GD.
