"They can if there is a 45% trade tariff on Chinse goods and there is a trade war with boycotts etc. The Chinese won't want to "go there" and will make a business deal with businessman Trump."
If there is a 45% trade tariff, all goods will be 45% more expensive as that is how high tarrifs will have to be to get American goods competitive with Chinese goods. That's not good for the working class.
"That's the spin our teams put out. Ford and Carrier were moving factories to Mexico to employ people on $3 an hour instead of the US rate. They weren't using robots. And the Apple factories in China are using Chinese people, not robots."
And if they can't employ people at $3/hr thereby avoiding massive capital expenditure, they'll bit the bullet and automate. 85% of manufacturing jobs have been lost due to automation. Manufacturing will never employ the same numbers it used to.
Apple, Carrier, they all have automation. They will all have more automation if they can't move. Carrier is still moving over 1000 jobs to Mexico btw despite all the corporate welfare Trump is handing them.
They aren't automated in China because it's more expensive to automate in the US than it is to hire cheap labour in China. That dynamic is changing, and lots of firms are already coming back to the USA and hiring miniscule work forces (sometimes under 100) and automating the rest, because it's cheaper than hiring people in China.
