I am not sure framing it as work ethic is right. It is simply the cost of labor. Some people might argue American's are more or less productive the hours they are working, which means just because someone from Taiwan is willing to be oncall 24/7, doesn't mean you'll have to hire exactly 3 American workers at 8 hours each to match productivity. You might need 5 because Americans truly are that lazy, or you might only need 2 because the on-call isn't that demanding since Americans are more productive.
Not saying any of these specifics are true, but framing it as work-ethic is not accurately capturing why it is more expensive to run factories in one country vs another.
To be clear, you are saying work ethic does exist and it is a factor but it's not the only factor, with productivity being another one?
