@freepatriot I have a cookbook from the early 20th century.
It contains methods for housewives to use to test whether or not pickles contain ARSENIC.
The reason this is in there is because unscrupulous manufacturers would use a small amount of Paris green, an arsenic based dye, to make pickles more visually appealing and retain their green color better. Of course, you had to test for it, because manufacturers wouldn't reveal it on the label.
Consider that manufacturers in the past marketed Dinitrophenol and dexamphetamine as ways for women to get slim and trim. Used heroin as cough syrup. Put highly addictive levels of cocaine in soda pop. Tetraethyl lead in gasoline.
Just take a gander at how many highly contaminated industrial sites have been left abandoned by conveniently bankrupt companies. Thousands of them.
I will admit that I am not a fan of the way the regulatory apparatus is used as an anticompetitive maneuver by industry incumbents etc.
But at the same time, manufacturers had AMPLE opportunity to prove that, without regulatory oversight or risk of lawsuits, they would act with proper care and caution for the wellbeing of their fellow man.
And with the opportunity they demonstrated that they would wreck the environment, poison people, get them addicted to dangerous drugs etc and sleep at night like babies.
