With his top priority of tax reform accomplished, Mellon increasingly turned over management of the Treasury Department to his deputy, Ogden L. Mills. After the 1926 elections, Mellon and Mills sought to cut the corporate tax and fully repeal the estate tax. The Revenue Act of 1928 did indeed cut the corporate tax, but the estate tax was left unchanged. Mellon also focused on the construction of new federal buildings, and his efforts led to the construction of several buildings in the Federal Triangle. In 1928, Mellon stated that "in no other nation, and at no other time in the history of the world, have so many people enjoyed such a high degree of prosperity or maintained a standard of living comparable to that which prevails throughout this country today."
