Also you are saying its proven it is not politically correct because its talked about and Biden has taken action for onshore more industries yet that does not even jive with the definition of politically incorrect. I think you are just responded to the original poster saying its not being discussed because its politically incorrect but that statement in itself does not make sense either. Something is politically incorrect when someone does not avoid language or actions that may offend another group. Something can be politically incorrect and still be discussed to death.

As for the last part about the anti-globalization crowd has yet to make a case convincingly, the same can be said on the flip said. For example the pro globalization crowd has not made a convincingly case for why we need to use slave/child labor overseas to make Nikes and electronics. If we produced these in the US, slave/child labor is generally illegal and this would not be a problem. Another example would be the fact the pro globalization crowd has not shown a convincing case for why would should be supporting other countries that commit massive humans rights abuses. Why should we send money overseas to a country that has reeducation camps they force citizens into?
