I don't mind spitballing a bit here.
I'm definitely left-leaning economically. I also am very much in favor of giving developing nations a chance at competing with our economy.
However, I would go more or less the opposite direction of what you're suggesting. I support allowing American companies to produce jobs on foreign shores _provided those companies follow American labor laws_. I'm in favor of pro-labor regulation and I'm also in favor of free international trade, but not where the latter is at the expense of the former. A totally free world market would circumvent our protections at home.
All this to say, I wouldn't really call what you're suggesting a benefit by any view.
