The Chinese government threw their own citizens under the bus to keep their wages low so that they could become the largest manufacturing superpower in the world within forty years. (If President Nixon were alive today he would be kicking himself because he opened trade with them). The U.S. had a similar trade problem before but it was between the states. Certain states allowed slavery and others didn't which created unfair competition in business.
The free states where slavery was illegal complained about unfair competition from the slave states in the south which led to abolishing slavery on the federal level, and then the slave states left the U.S. and created a new nation called The Confederacy, which led to the Civil War which killed over a third of the men in this country. Luckily, China and Bangladesh are not part of the U.S. and so we don't have to confront them or even have a conversation with them. The onus of the problem is the American companies that sent our manufacturing jobs there. Now they're the proverbial slave states. They are within the United States' jurisdiction and so that's who Capitol Hill and the White House would confront.
They'll do anything to protect their "right" to continue sending American jobs overseas. Over the last forty years they've funded politicians' campaigns, broadcast ad campaigns across America to bolster their image, they created nonprofit organizations overseas to make themselves look like they care, and after all of that they're still paying factory workers in Bangladesh $38 per month.
At this point the key question is this: If Capitol Hill and The White House force them to quit their slavery habit, will some states declare their independence from the U.S. and create a new nation that is similar to The Confederacy in 1861? Would China support them?
San Francisco used to be a factory town and while those jobs were being moved out there was an enormous influx of immigrants from China and Taiwan. It's a coincidence, but now all of the factory jobs are gone and the former workers who would have rallied to get them back are gone or dead, and the people who replaced them know nothing about San Francisco's former factory-driven economy. Coincidentally they come from the places where those jobs went. There's a Chinese cable TV station called CCTV that constantly broadcasts propaganda to bolster China's image, and their Asian viewers throughout the entire San Francisco Bay Area eat it up, not realizing that China's money comes from the U.S., Canada and Western Europe.
If the 1861 slave nation called The Confederacy comes back, renamed something else, this time supported by China instead of plantation owners in Mississippi, will the new nation's capital be San Francisco? Over a third of the residents are Chinese and Taiwanese, and San Francisco has the largest Chinatown in the world and a second one on Clement Street in the Inner Richmond District.
Could it turn into an internment camp? During World War II Japanese Americans were sent to internment camps. Americans won't tolerate that kind of abuse anymore and so it's extremely unlikely, but if it were to happen San Francisco could become a target.
