If you were to put something in a population to keep them down for generation and generations to come, it would be lead… It’s a well-known, potent neurotoxin. There’s tons of evidence on what lead does to a child, and it is one of the most damning things that you can do to a population. It drops your IQ, it affects your behavior, it’s been linked to criminality, it has multigenerational impacts. There is no safe level of lead in a child.
