There is an important debate going on about just how progressive a tax system has to be in order to serve progressive political ends. The debate was instigated by Edward Kleinbard, writing in the New York Times. Kleinbard argues that we should avoid steep increases in taxes on the rich in favor of “boosting revenue over all,” on the grounds that the American tax system is already the most progressive in the world, and that in any case we should focus on the progressivity of the entire fiscal system, not just the taxation side of that system. Some of the more interesting critical discussions of Kleinbard have been produced by Mike Konczal, Steve Waldmann and Matt Bruenig.
From my vantage point, building a bit on the neo-socialist approach I sketched in my previous post, tax policy should be informed by ambitious egalitarian goals. Contrary to Kleinbard, I believe we do need to tax the rich much more heavily. But the primary point of these taxes is not to finance the spending side of the nation’s fiscal program. Here are the two key points I think need to be made:
The best reason to tax the very rich heavily is, initially, to make them less rich.
The best subsequent reason to tax riches heavily is to prevent people from becoming very rich again.
The long-term goal of neo-socialist political economy is to build a more equal and a more democratic society, a society in which we have done everything we realistically can to level the vast differences in income, wealth, social status, education, political power, cultural participation and human dignity that currently prevail in the United States. Toppling the looming citadels of concentrated private wealth will help to advance democracy, broad prosperity and justice. That’s a good enough reason to do it, all issues of public revenues aside.
