What do you think the per capita amount of interest people in the US would have to pay on this year's deficit amounts to (assuming borrowing is at current 10 year Treasury bond rates):
Poll "We're looking at a $643 billion deficit for 2013..." --
CBO via Yglesias At 1.7%, which is a close approximation to whatever the 10 year note is today, that's about $11,000,000,000. Divided by 310,000,000 people gives you $35.26. So $30 is the closest answer.
