Dominic Cummings Eugenic theory

Dominic Cummings, special political adviser to the Prime Minister, believes that the rich have superior genes. He said so in a tedious lengthy paper he wrote when he was an adviser to Gove.  Gove was an education secretary best known for his ignorance of education.

The theory is a rehash of the long-discredited concept of eugenics. Eugenics was popular with the Nazi Party

Is Boris Johnson an example of the superiority of the rich? If so I am very satisfied with my inferior working class genes, thank you.
