We need to be very worried
As I see it, the only reason why main stream beltway Democrats would advocate a tax cut at the expense of social welfare programs is because they see near term economic trouble. Congressional Democrats would have access to much of Greenspan's data. If Greenspan gave them a talking to, telling them that we're on the verge of a 1929 meltdown then they would advocate tax cuts to prop up consumer spending. I think we're in deep trouble.
