It is strange, almost bizarre, that the President who did the most harm to the working class and middle income family in the USA is not a Republican President. He is a Democratic President. Who is this president and what harm did he make?
He is Bill Clinton. During his term, he signed the NAFTA (North American Free Trade Agreement). It caused many jobs to move from the USA to Mexico and Canada.
This is followed by other trade agreements of the same pattern, e.g. the Permanent Normal Trade Relations (PNTR) with China and other countries. Although the PNTR agreements are made by subsequent presidents, Bill Clinton opened the door for the following disastrous trade agreements.
