re: Larger impact to Louisiana economy

I don't know that there's any real way to quantify it, but it certainly is an interesting question.

As has been said, the oil industry supports a lot of ancillary jobs. Posts before this one mention many of these positions.

The seafood industry does as well, though. You're not just talking about the people going out in the boats to get the shrimp, oysters, crabs, etc. You're talking about the marinas they run out of and the people who work there (and deliver supplies to there), the people who transport the seafood to the markets, the people who work in the markets, the restaurants who buy the seafood and all the people who work in that area. There's the recreational fishing side of things, too. The people who sell and service boats, trailers, motors, parts, the rods, reels, nets, and other equipment, the marinas where those boats launch from, the camps that are constructed and outfitted, and on down that chain.
