Progressives are intellectuals and saints.
Progressive intellectuals ignore Hayek, who argued that the population at large knows more information than any intellectual. Intellectuals propose that the intellect of the normal person is inadequate, especially when it comes to their field of expertise.
Education changes the nature of the human to superintellect(moral(religious)) from merely intellect(moral(religious)).
In addition, normal humans have feelings, ethical stances, and ideas that always have unintended consequences (hence, are responsible for the social surd).
In short, the decisions of normal people are always stupid.
This, in a nutshell, is the Progressive Doctrine of Original Sin. Normal people are always stupid. This is similar to the Doctrine of Total Depravity.
