Maybe we should consider the Trump trade war to be a wakeup call. Economic Policy both national and foreign should not be the responsibility of a president and his pollical cronies, first because they are not qualified and second because economy policy needs to be consistent across administrations and based on sound economic principals, not presidential polls and fund raising.
The Federal Reserve Board is the most nonpartisan organization in Washington and most probably the most qualified organization to set economic policy. Board members serve for 14 years with terms staggered so that one expires every two years so their tenure can cross 4 presidential administrations. They report to congress not the president. Also if the US Trade Representee reported to the Fed Board or Congress we could have a consistent long term trade policy that would make it possible to eliminate the trade deficit over a period of years. That will never happen with our current organizational structure.
