I am not sure why anyone believes that any legislation to impose tariffs would ever make it through congress, the senate, or the president. The same people that pushed for NAFTA, TPP, and any other free-trade agreements have already laid the groundwork so that should the populace finally wake up, it will be far too late to do anything. In other words, the people that own our elected officials will continue to own whoever gets elected in the future. Should the American populace decide that this whole globalization thing is bad and elect representatives who say they will do something, these lobbyists will either shut down the legislation before it becomes law, or just pick up their toys and leave the country. Companies are doing it now, and it's only about some 20% tax difference on corporate profits. Do you really think that any company would stand for being told where they have to manufacture for very long before they decide to go somewhere else?
