It’s a matter of information. “Creative” people take traits essential to human nature, love leadership, etc., to create “alternate realities” on TV cinema and literature to make money from a gullible public selling them products and advertisements instead of using their creative resources to teach society how it should use these essential human traits to live in the natural environment.
