Models. Models built by sinecured credentialists for careerist advantage; enabling anti-human busybodies, corporate elites and autocratic politicians to demand policies commanding the lives of ordinary people.
That both sets of models, and the ensuing policies, have been failures is not a coincidence. Neither is the refusal of the busybodies, elites, or politicians to apply the policies to themselves.
For example, flying from their mansions to environmental conferences in private jets and ignoring social distancing in BLM marches.
