Why are we subsidizing BP at all?

BP was reaping sizable tax benefits from leasing the rig. According to a letter sent in June to the Senate Finance Committee, the company used a tax break for the oil industry to write off 70 percent of the rent for Deepwater Horizon — a deduction of more than $225,000 a day since the lease began.

With federal officials now considering a new tax on petroleum production to pay for the cleanup, the industry is fighting the measure, warning that it will lead to job losses and higher gasoline prices, as well as an increased dependence on foreign oil.

But an examination of the American tax code indicates that oil production is among the most heavily subsidized businesses, with tax breaks available at virtually every stage of the exploration and extraction process.
