...in his seminal 1887 article, “The Study of Administration,” published in the same year that the first modern regulatory commission, the Interstate Commerce Commission, was created, Wilson explained that he wanted to counter “the error of trying to do too much by vote.” Hence, he admonished that “self-government does not consist in having a hand in everything,” while pleading for “administrative elasticity and discretion” free from checks and balances. Not surprisingly, Wilson’s conception of government run by administrative “experts,” unconstrained by popular consent, runs up against the traditional understanding of the Founder’s Constitution, with its tripartite system based on a separation of powers among the legislative, executive and judicial branches.FDR greatly amplified what WW started.
FDR didn’t start the movement, but he was in fact the one who actually did what they had wanted. He inherited a government still functioning mostly along constitutional means and left it Arbitrary government after him.
