Buffett wants to pay more tax

The United States' second-richest man has delivered a blunt message to the Bush administration: he wants to pay more tax.

Warren Buffett has complained that he pays a lower rate of tax than any of his staff - including his receptionist.

Buffett, who is worth an estimated $52 billon, said: "The taxation system has tilted toward the rich and away from the middle class in the last 10 years. It's dramatic; I don't think it's appreciated and I think it should be addressed."

During an interview with NBC television, Buffett brandished an informal survey of 15 of his 18 office staff at his Berkshire Hathaway empire. The billionaire said he was paying 17.7 percent payroll and income tax, compared with an average in the office of 32.9 percent.

"There wasn't anyone in the office, from the receptionist up, who paid as low a tax rate and I have no tax planning; I don't have an accountant or use tax shelters. I just follow what the US Congress tells me to do," he said.

Buffett also took a pot shot at hedge fund managers. He said: "Hedge fund operators have spent a record amount lobbying in the last few months - they give money to the political campaigns. Who represents the cleaning lady?"

His intervention comes amid an increasingly rancorous debate on Capitol Hill about tax. Shortly after taking office, President George W. Bush pushed through $2 trillion in temporary tax cuts, including sharp reductions for high-earners. These expire at the end of 2010 and the White House wants to renew them.
