Of course it has, it was instigated during the Jimmy Carter era, which was probably the most depressing time that the United States has ever suffered.
No, it started back in the Nixon administration back in the spring of 1974. It wasn't till the summer of 1986 that a partial repeal was approved by Congress. I still can't figure out why it wasn't repealed in 1981. The total repeal occurred in 1995 after Republicans swept congressional elections in 1994.
