If Amnesia, Alzheimer’s Disease, Addiction, and Hysteria are bad for the individual, why would they be good for an entire people?

European people are told to forget their history(amnesia), forget who they are & where they are(Alzheimers), wallow like pigs in moronic pop culture opium(addiction), and become wildly PC(hysteria).

Why is that something that is bad for the individual is prescribed to an entire population?
