3 Brane universe

All Trump did (putting aside salacious trivia that didn't bother Democrats when Bill Clinton did it) was try to put the U.S. back a bit from the FACT the CLINTONS sold 1/3 of America's production of goods to the CHINESE by using horrifically-lopsided trade deals.

The US has never had - under Clinton or any other president - a trade deal with China. A group of new large retailers such as Walmart, Target and Home Depot moved sourcing to China and other developing markets with the very enthusiastic support of the consumer market. There is no way Clinton could have interfered with this shift without a whole bunch of free marketers led by Gingrich absolutely crucifying him.

Clinton's solution was NAFTA. NAFTA has worked well except (for you Trumpites anyway) that it helped brown people - oh alack a day.

Given your belief the US had a trade deal with China it would not be surprising to learn you are unaware of the role protected markets played in creating and exascerbating The Great Depression as well as the cycles of boom and bust the world experienced in the latter half of the 19th Century.

Blue collar workers in the US are not suffering from free trade. Rather they are suffering from the Corporate onslaught against organized labor. Had the US adopted a union friendly scheme such as Germany where unions are protected by law and have mandatory seats on the board of directors of corporations US workers would not be in the mess they are now. And of course it would be a cold day in hell before Trump or any Republican made any attempt to encourage organized labor.
