We have too long abrogated our duty to enforce the separation of powers required by our Constitution. We have overseen and sanctioned the growth of an administrative system that concentrates the power to make laws and the power to enforce them in the hands of a vast and unaccountable administrative apparatus that finds no comfortable home in our constitutional structure. The end result may be trains that run on time (although I doubt it), but the cost is to our Constitution and the individual liberty it protects.
