“The cost of government has risen by about 20 percent since 1975, when taxes accounted for less than 30 percent of the gross domestic product of the organization’s member countries. The increase in the ratio of taxes to gross domestic product since 2000 occurred despite cuts in tax rates in most of the countries, said Christopher Heady, head of tax policy for the organization.
But even with reduced corporate tax rates, Mr. Heady said that worldwide corporate profits had risen so sharply since 2002 that the amount of money flowing into government coffers had increased.
He attributed most of the long-term rise in taxes to expanded social insurance programs, like universal health care and pensions.”
“Taxes in the United States — from the federal income tax and Social Security tax to local property levies — rose to 28.2 percent in 2006, from 25.6 percent of gross domestic product in 1975, the O.E.C.D. said. It reported that American taxes peaked at 29.9 percent in 2000, slipped to 26 percent in 2004 and then began rising again, a finding consistent with recent statistical tables released by the Internal Revenue Service.”
