That said, you are correct, and oil spill this size obviously effects a large group of people. I don't think anyone is arguing that point.
That said, the economic impact of the deepwater drilling moratorium (speaking for Louisiana here) is devastating as well. It is costing hundreds of millions (billions even) in lost economic activity, lost tax revenue (federal and state), and potentially putting people out of work for good.
Already we have seen more than 1 rig be contracted out to other areas, and they are leaving the Gulf. That means they are not going to be coming back when the moratorium is lifted, and the workers who serviced/worked on this will not be able to suddenly have their jobs back.
All of this after all of these rigs passed another safety inspection by the Department of the Interior.
