The editorial pages of last Sunday's New York Times carried an extraordinary plea from the world's third richest man.
In a strongly-worded opinion piece, 80-year old multi-billionaire Warren Buffett slammed the iniquities of the United States' tax system.
But unlike most people who fulminate against the taxman, the Sage of Omaha was not complaining that he pays too much to the revenue.
Quite the reverse: in what is surely a first, Buffett was arguing that under current US tax regulations, he, along with the rest of America's obscenely rich, are failing to pay their fair share.
Like other billionaires, Buffet doesn't receive a salary, so he doesn't pay payroll taxes. Instead he earns his income in the form of stock dividends and capital gains, which are taxed at a lower rate.
As a result, last year Buffet paid only 17.4 per cent of his income in tax.
