BP has been using prison "work release" labor to clean up the spill. When the public took notice of the prison garb, got rid of it. The prisoners are not being paid, but BP is...$2,400 for every inmate they hire (which, BTW, explains why the cooks on the rigs are all work-release prisoners, as I've been told).
And this: "...And that's not all we're subsidizing. For example, BP, which rented the drilling rig from Transocean Corp., used a special tax break to write off 70 percent of the rent it paid. Seventy percent! This added up to a savings of $225,000 a day for BP..."
And this: "...Again and again, BP has promised that it would pay all cleanup costs for the mess it made. Now, however, the British-based oil giant has quietly told investors that it expects to get a $10-billion subsidy from Uncle Sugar to help cover the costs..."
