Statistical sleight of hand

Mr. Gross is uncharacteristically trying to pull the wool over our eyes with this most recent story.
He suggests that unemployment is worse than it appears because "traditional methods of measuring unemployment...might not accurately portray the economic situation." As evidence he cites the U6 statistic which tries to measure underemployed and discouraged workers.
He notes, but for some reason ignores, the fact that the ratio between the U6 and the official unemployment rate is relatively constant. This, though, is the crux of the matter: As long as this ratio is constant, then the official unemployment rate *is* a useful tool for comparing the depths of employment problems during different recessions. The official unemployment rate isn't as bad as in the early '80s, so there's no reason to believe that the total fraction of un/under/discouraged workers is worse now than it was then, either.
If Mr. Gross could present evidence that disproportionately more workers were underemployed and discouraged, rather than traditionally unemployed, in the current crisis, then he *would* have a story.
