Since the creation of the federal reserve... the USD has been in a constant inflation. USD has lost over 98% of its value. From $20 an ounce when gold was redeemable with fiat to now...$1300 plus an ounce. You can’t trade your fiats for gold in banks. People who hold gold are call “hoarders .”
President can make an executive order... but any who try will kiss his/her life goodbye. Just ask JFK... Bernie Sanders was anti fed... you think he has any chance to be elected?
No chance one person can get rid of the federal reserve. It will take a revolution.
