There’s a discontinuity in this conspiracy theory: you haven’t explained how endocrine disruption pacifies the population (or anything else, besides disrupting their endocrine system).

As always, the more parsimonious answer is that plastic is cheap and that nobody is incentivized to determine the long term cost of usage/exposure. You don’t need a conspiracy to explain the outcomes here; profit motive suffices.

I know certain financial interests love this discontinuity because we can't discuss fully without getting into taboo subjects. I prefer to leave it to the reader to infer how hormonal dysfunction might lead to a passive demeanor.
