No, it isn’t Islam — it’s Marxism.

This seems related, somehow. How is Warren Buffett like the Pope? They’re both completely clueless about how economies work:

The great advantage of competition in markets is that it exhausts all gains from trade, which thus allows individuals to attain higher levels of welfare. These win/win propositions may not reach the perfect endpoint, but they will avoid the woes that are now consuming once prosperous economies. Understanding the win/win concept would have taken the Pope away from his false condemnation of markets. It might have led him to examine more closely Spain’s profligate policies, where high guaranteed public benefits and extensive workplace regulation have led to an unholy mix of soaring public debt and an unemployment rate of 20 percent. It is a tragic irony that papal economics mimic those of the Church’s socialist opponents. The Pope’s powerful but misdirected words will only complicate the task of meaningful fiscal and regulatory reform in Spain and the rest of Europe. False claims for social justice come at a very high price.

A similarly harsh verdict must be rendered on Warren Buffett, whose much discussed editorial in the New York Times foolishly condemns the very economic system that allowed him to flourish as an extraordinary investor. Rhetorically, Buffett’s editorial reads like the confession of a man who got away with putting his hand in the cookie jar. He starts by insisting that in difficult times the principle of “equal sacrifice” should guide collective deliberations. In good autobiographical fashion, he then admits that the current tax system has allowed him to get away with paying just under $7 million in taxes this past year, which works out to be 17.4 percent of his $40 million personal income.

In Buffett’s utopian world, higher taxes, including higher capital gains taxes, magically generate the revenues needed to eliminate the current massive deficit. For this bold proposition, we have Buffett’s personal assurance that he has never seen capital gains rates that approach 40 percent “scare off” large or small investors. This is a simple case of sampling error, for those people who are scared off by high capital gains taxes don’t beat a path to his doorway in the first place. It would have been better if Buffett had addressed the “lock-in effect” with respect to capital gains. People only pay capital gains when they sell their stock. Accordingly, investors are highly sensitive to the capital gains rate, because why sell if the net proceeds from the sale are so small that they more than negate a higher rate of return from a shrunken capital base?

On this logic, lower capital gains rates generate more tax revenue for the federal government.

Of course, according to the president, it doesn’t matter. All that matters is “fairness.”
