That's a good point.
Where's the line between knowingingly circumventing the spirit of the law by following the letter.
For example Teflon has been replaced with chemically similar compounds that just aren't Teflon. It'll take decades for the studies to come in, in the mean time every human is being exposed to these chemicals in significant amounts.
Then we have bpa, Neonicotinoids and other pesticides. We have cases where companies knowingly sell talc contaminated with asbestos for decades.
We know these products kill people, we now the companies that make thenknow they are killing people and yet we can't claw back decades of fraudulently acquired profits and revenues?
Imo, we should treat these behaviors like Nazis where everything they touched gets seized, even decades later. If that ruins some lives, well, whose worse off? The injured class or the child who inherited blood money?
