It Is Doubly Difficult to Get Out

I am reading William T. Vollmann's second-latest enormous book -- "Imperial" -- and I came across this apt, wonderful, and terrible paragraph which addresses why the New River (in Mexico and California) remains so terribly polluted.

Maybe the New River wasn't anybody's fault, either. People need to defecate, and if they are poor, they cannot afford to process their sewage. People need to eat, and so they work in the maquiladoras--factories owned by foreign polluters. The polluters pollute to save money; then we buy their inexpensive and perhaps well-made tractor parts, fertilizers, pesticides. It is doubly difficult to get out. And it's all ghastly.

Sigh.
