The constraints on policy choices resulting from our unprecedented deficits
The psychological and economic factors that have led to our present version of the realization rule
The theoretical possibility of adjusting tax burdens to reflect different amenities in different areas of the country
Intergenerational (in)equity as reflected in the Social Security tax-and-transfer program
How our tax system would function in a world of deflation
