so many small business owners in louisiana and their employees have been decimated by the disaster. >> the question is what happens next? where are people going to make a living? do they stay there? do they have to leave? the psychological trauma which is basically the second major trauma after katrina in five years is an overwhelming challenge for people. >> oil is one of the biggest industries in louisiana and a big source of tax revenue for the state. >> louisiana needs the oil industry to survive, and to some extent, the oil industry needs louisiana, because louisiana generally has pretty lax environmental laws and very lax enforcement. it has a very good infrastructure to support the oil and gas industry. >> critics claim big oil has thrived in the state's notoriously loose and corrupt political system.
