It was with some distress that I learned that the brother (Adrian Vermeule) of a friend of mine and a prominent behavioral economist or ally thereof (Cass Sunstein) had penned an article that is serving to legitimate Trump's consolidation of power in the executive branch of the federal government. The Constitution, they argue, gives the executive broad and scarcely limited authority. Together with arch-conservative Curtis Yarvin's argument that the President should be the CEO of the country we see a lot of pieces falling into place to legitimize Trump.
The problem with the "unitary executive" or "president as CEO" argument advanced by Vermeule, Sunstein and Yarvin is that the idea of what an executive should be was pretty underdeveloped in the 18th century. We have learned in the intervening quarter of a millenium that checks on corporate executive power are all important. Thus we have corporate boards (and enhancements to them ushered in by things like Sarbanes-Oxley), capital markets, competition from other vendors, etc. Experience has shown that unchecked corporate power often brings bad results, because the strong affinity between sociopathy observed in CEO types is a real issue. Good CEOs work with and receive counsel from the most competent and empowered direct reports they can get. Or they flame out. And give rise to things like Sarbanes-Oxley.
Overall the "intentions of the Framers" orientation in constitutional law is just foolish. I think the founding fathers would roll over in their graves if they knew the extent to which they are fetishized, though really I think that the whole thing is a straw man for holding onto power. I think the founding fathers, if they could talk, would want us to be arguing in perpetuiry about principles and how to govern best, how to mediate between the claims of individuals and society as a whole.
But at a very high level, if the founding fathers had wished for the executive to dominate the legislature, why would they have led with enumerating the powers of the legislature in Article I and then come back to the executive in Article II? Yes they limited the legislature, but they started there for a reason.
