I grew up in Cancer Alley. Here's my old neighborhood: https://maps.app.goo.gl/3DZbiz8Bgyx5tx7v9

That wedge surrounded by green is a neighborhood that was created by landfilling a patch of swamp and building a levee around it. The northeast side of the wedge is the "nice" part of the neighborhood. You can see the houses are much bigger and there is a golf course running through it. There's a country club and lot of very nice houses. That's where a lot of upper level oil company employees live. (We lived here, my stepfather was a research chemist at DuPont.)

The southwest side of the neighborhood (much of it literally on "the other side of the tracks") is the cheaper houses and some apartments where a lot of blue collar employees work.

Zoom out a bit and you see Shell Norco to the northwest, the very heart of (and cause of) Cancer Alley. Ormond Estates was basically created to be a commuter neighborhood for Shell. Across the river is Dow Chemical. Look east and you see the IMTT St. Rose chemical plant. Keep going upriver and you get to DuPont and the Marathon Refinery.

Most of the executives responsible for cancer here do live in the area. People of all stripes have an impressive ability to maintain cognitive dissonance and live in denial when they are incentivized to do so.

Southern Louisiana is an intense microcosm of this. Seafood is one of the biggest industries there and you would think the local culture would be intensely protective of the environment, especially after the Deepwater Horizon disaster. But environmentalism is woven into liberal culture that is in opposition to the religious conservative culture of the area, so it often gets actively rejected even though poor people in Louisiana are the ones who suffer for their choice.

"Strangers in Their Own Land" is an excellent social science book if you want to know more about the area.

I live in Cancer Alley and people down here drink the koolaid. Cut to Midgely pouring TEL all over his hands.
