Incentivize companies to do it. I also think a lot of the buying public may look at buying shyt made in China a little differently.
Long as the shyt is cheap and affordable most americans will still buy from china.
Most americans won't even flip a product over to see where it is made from.
Also from my history working internationally in manufacturing. China has a 20 year head start on places like India, Mexico and parts of africa from a logistics and supply chain standpoint. Which is why even though China's labor rates are higher. Companies still offshore their manufacturing to china.
For example when I worked in India and Mexico. If our 300k manufacturing machine broke down it would take 2 weeks to get it fixed. Why you might ask? Because the technician who can fix it is located on another side of the country and is the only person in the region that can fix it.
When I worked in china and that same 300k machine broke down. I could get someone to fix it in 1 day. Because china had multiple companies that could fix the machine and those companies were all located within miles of the facility I worked at.
Same with companies that make tool fixtures as well. Which is the heart and soul of manufacturing (tool fixtures) outside of the assembly workers.
Now realize the estimated cost to the company I worked at for this machine being down a day was between 100k and 200k. So the machine being down for 2 weeks meant a loss of 1 million dollars at lest.
All of this is a reason why even though China's labor rates are higher (than mexico, india and parts of africa) and have higher shipping costs (than Mexico). Companies still move their manufacturing to china. Cause labor rates does not mean cheaper manufacturing costs when factoring in line down time and ect.
The investment in china the west made in the 70s still has china eating good from a supply chain and logistics standpoint.
