Charles Krauthammer‘s latest National Review Online column dissects the facts, rather than the rhetoric, associated with President Obama’s so-called “Buffett rule” for imposing a minimum 30 percent effective tax rate on millionaires.

Okay. Let’s do the math. The Joint Committee on Taxation estimates this new tax would yield between $4 billion and $5 billion a year. If we collect the Buffett tax for the next 250 years — a span longer than the life of this republic — it would not cover the Obama deficit for 2011 alone.

As an approach to our mountain of debt, the Buffett Rule is a farce. And yet Obama repeated the ridiculous claim again this week. “It will help us close our deficit.” Does he really think we’re that stupid?

Hence the fallback: The Buffett Rule is a first step in tax reform. On the contrary. It’s a substitute for tax reform, an evasion of tax reform. In three years, Obama hasn’t touched tax (or, for that matter, entitlement) reform, and clearly has no intention to. The Buffett Rule is nothing but a form of redistributionism that has little to do with debt reduction and everything to do with reelection.
