Thanks for the writeup. From someone in the industry it is really meaningful, at least to me.
When I began working residential const. in the '60's, the plumbers were still doing lead joints on their cast iron sewer fittings, so there was a lead pot going a lot of the time. None of us worried about it, because we didn't know any better. Ignorance is bliss. I used to take some lead home and pour my own surf sinkers, and never knew there was any danger. I also did my own brakes, and didn't know about asbestos dangers either.
Funny, our country outlawed lead in paints in the 70's, I think, but, in Germany, when lead miners began having problems, they outlawed it in 1913, I think.
So, just like Johns Mansville's memos proved with asbestos, lead's dangers were widely known for years in this country, but ignored, because it would cost money and jobs to deal with it. Instead, it cost kids their physical and mental health.
"What profit a man, that he gain the world, but lose his soul?"
The politicians who turned a blind eye and deaf ear to lead's dangers had no souls.
