"What if a president cut Americans’ income taxes by $116 billion and nobody noticed? It is not a rhetorical question. " This is the strong lede in a story about the tax cut hidden in the stimulus package. We are told that the Obama administration intended this piece of the legislation fly under the radar, so that the additional cash would be spent and not saved in order to help to stimulate the economy. But no where in the article is a key piece of information. What was the news media's culpability in this? Why were so few Americans unaware of the reduction in their withholding?
