You're right about the Civil Rights act, I had misremembered. However Kennedy met with MLK and proposed the Civil Rights act.

Blaming "business executives" is unhelpful as an explanation because "business executives" is not a static group. Business executives who moved their manufacturing to China or Mexico made their businesses more profitable or at least preserved their profits, because they saved a ton of money. Business executives who kept manufacturing in the U.S. generally were outcompeted and they were either replaced, their businesses shrunk, or they were forced to reorient towards higher end, smaller markets.

NAFTA, MFN/PNTR for China, and then WTO membership for China is what created this situation. This was a total disaster for American labor. All of the things that Perot warned about with the "giant sucking sound" were exactly what happened.

Underpaid workers in other countries most certainly did get a lot of that money. Have you seen what has happened to wages in coastal China over the past 25 years? Most of that money comes from exports, and a large portion of those are to the U.S.

Perot's other policies don't necessarily track as "pro-labor." My point was just that the two biggest things that negatively affected American labor in the past 40 years were passed under Clinton. Interestingly, the vestiges of the labor-oriented Democratic party were still there in Congress, and large majorities of Democrats in the House voted against NAFTA and PNTR for China. On NAFTA, this result wouldn't even be possible today due to the "majority of the majority" way that the House is run.
