The support behind VAT and other consumer taxation shows us how the wind is blowing on Washington weathervanes. There are other winds, however, outside the Beltway. The fate of England’s Charles I in 1642, of France’s Louis XVI in 1789-93, of Russia’s Nicholas II in 1917-18, of Indiana Senator Albert J. Beveridge in 1922, of House Ways and Means Chairman Al Ullman in 1980, and Japanese Premier Uno in 1989, all manifest a tendency of voters to retire statesmen who identify with consumer taxes.
