Nothing frustrates me more than when I hear the far left say that we should allow China to continue on their path. The right will scream that we are letting them get away with murder (of course, they do not mean it literally, but it is ), however, they refuse to put a tax on goods even though any company can easily get out of it: SImply have the parts manufactured in clean states/nations.
Now, to be honest, we should not do a tariff (which is a tax on goods that move in/out of a nation/state). Instead, it should be a tax on all goods that are consumed locally. And it should be BEFORE the retailer, or if mailed, as part of that. With this approach combined with real monitoring,and normalizing based on emissions / GDP, we can reward those nations that clean up, while going after those that are chosing to emit. In addition, if a nation does like China and manipulates their money by dropping its value, that is fine. It simply means more emissions / $ GDP. As such, it behooves nations to NO cheat at it.
