As far as Shapiro's alleged fallacy, that was a fair response IMO to Cenk's own fallacy. Cenk attempted to link high growth with high taxation and inferred causation through correlation. This is a well abused tactic by pundits from both sides. Cenk said nothing of baby boom, post depression, or the ensuing stagflation that was caused by excessive government social program spending funded by debt and combined with policy fueled by a modern leftist's wet dreams.
The context in which I've always heard Cenk's argument is that high tax rates do not necessarily impede high growth. Not that they're linked in that high tax rates result in high growth. I'd think Shapiro knew better - but decided to play to the crowd and create a straw man argument.
