From a column by Jabba the Economist in the Miami Herald:
Bill Gates, Paul Allen, Steve Ballmer and the other millionaires and billionaires of Microsoft are brilliant, hardworking, entrepreneurial and justly wealthy. But only the first 5 percent of their wealth can be justified as an economic incentive to encourage entrepreneurship and enterprise. The next 95 percent would create much more happiness and opportunity if it were divided evenly among U.S. citizens or others than if they were to consume any portion of it.
So the entitlement that hard-working Americans can claim to the fruits of their labors requires being "justified" on the grounds of incentives? How about "justifying" it on the grounds of freedom? What possible argument in favor of stripping away property rights can come from Brad DeLong's opinion, or anyone else's, that some fraction of those fruits would make other people happier than it makes its creators? I am most assuredly not concerned with the happiness it gives Brad DeLong to appoint himself the arbiter of everyone else's happiness, and to imagine the thrill of the power that would come with deciding how everything should be distributed to maximize that happiness. Let DeLong create something of value for once in his life, and let him be in charge of distributing that.

Update... a reader who asks for anonymity thinks the headline for this post should have been "Brad DeLong's Conception of Calorie Rights," and he suggests the following rewrite:

Brad DeLong and other overweight economists earn good money from public institutions and are big eaters and obese. But only the first 50 percent of their calories can be justified as a dietary requirement for healthy living. The other 50 percent would create much more happiness and opportunity if it were provided to starving U.S. citizens or others than if they were to consume any portion of it.
Update 2 [2/2/2007]... Reader Forbes Tuttle makes a good observation:
In taking up the subject of the Microsoft Millionaires, but especially the billions of Gates, Allen, and Ballmer, whose wealth is a result of the appreciation of Microsoft's market capitalization, DeLong is proposing the policy of a 95% tax on capital (wealth). As class warfare, this may get some juices flowing, but as economic policy, this puts DeLong's party--the Democrats--in league with Karl Marx, who preferred 100% of the capital to be in the hands of the state. As regards the consequences of such a policy, I'd suggest DeLong's 95% tax on wealth is a distinction without a difference, when compared to Marx's 100% state control.
