Volcker, as with any human being is not perfect. Only our creator can claim that title. So we take the good in proportion to the bad.
A strong and responsive Congress would restrain a POTUS's dumb ideas, and Conservatism also has great momentum at the state level.

Our energies must be focused toward defeating the Thug in Chief and his army of zombies.
