Yup costing lots of workers. But the main reason for all these agreements? Because everyone wants things cheap. Especially all the cheap shit they buy from China every week that they dont actually need. Ask and ye shall provide. Also, people dont want to pay $5.00 for an avocado or meat that costs $40 a pound. Add a couple thousand to the cost of a basic car. Lots more expensive to make stuff here between raw materials, land prices, executive pay, labor, stricter controls and all the rest. Not even taxes anymore since companies often get sweetheart deals to move to different areas.
So... to get jobs back here... are you willing to pay for it? Or will you insist on prices to remain the same?
