Organized labor sure thinks it is. And it’s not like these free-trade jobs are going to organized labor elsewhere, it’s going to people being exploited with no recourse.
And yes, I think it’s very likely labor is a major component of shipping cost increase from the Jones Act, and would love to see you provide literally any proof otherwise, because I’ve shown you a study of costs that directly compares them. I am notably not saying it’s only cost, but it is almost certainly a major driver, for the simple fact that labor is almost always the major cost in a business and why capital is so desperate to offshore or replace it.
I’ve answered your question. Why is your position aligned with capital?
