Boycotting BP would only hurt the USA.
First, there is no way to know what oil you are putting in your car. Like maple syrup or milk in Vermont, oil goes into cooperatives and is then shipped to various outlets to be sold under the outlets’ brand names.
Second, you would be hurting the retailer who could well be your neighbor’s brother, your local grocer’s uncle or other town guy who is just trying to make an honest living for himself and his family.
Third, BP must be profitable to fund the escrow account the injured parties along the Gulf coast are counting on for financial help. I started to say “to make them whole.” Nothing will make them whole. They are the victims of a tragedy; perhaps a little better off than the person whose house is disintegrated by a tornado. Mother Nature takes no blame; gives no relief.
This is a case of frustration at one’s inability to admonish or punish someone we feel has wronged us.
