I was tear-gassed protesting free trade. Can I now say, “I told you so”?

I think realistically the best case scenario is bespoke tariffs plus resurgence in union density and militancy. Our own labor standards are too low for sustainability at this point so teaming up with other countries with similar standards would still not solve the issue at home. We're still on an uptrend when it comes to inequality and we know it leads to instability at some threshold. We need to significantly curb the amount of money/wealth going to the top and instead direct it to the working class.

is it assuming that everyone thought globalization was a good thing?

Yes. And many did. The 1988 election was mostly about free trade with the US, which the pro-free trade party won. The general assumption was that some people would lose their jobs, but prices would go down.

And that's what happened. But it turns out that lots of people lost their jobs, and certain sectors shrank dramatically.

Globalization IS a good thing. Many people didn't like globalization and free trade because while being a huge productivity boost overall it was also a large wealth transfer to many of the poorest nations on Earth. And they used this math to make some very convincing arguments that we were "falling behind" and "living standards were declining" and maybe in some cases the speed of that wealth transfer did go too far. But mostly what was really happening was simply that other countries were catching up and this is not a bad thing unless you consider those people sub-human.

I don't consider people in other countries sub-human so I think our goal should be to make the entire world a nice and equitable place to live for everybody, because having a nice world that everyone can live in benefits us personally and the rising tide will lift all boats and we can finally start to put all this horror and war and injustice behind us and try to focus on things that actually improve our civilization together. This is not a zero sum game, we do not have to steal from the very poor to make our own poor richer, we can gradually fix the historical inequality to bring everybody up to the same level without causing too much stress to ourselves if we just adjust our expectations a little and frame it in the right way.

The thing that was actually bad about free trade was that some very non-democratic, non-free countries abused it, monopolized manufacturing of entire industries and bribed us with very cheap products about it so we didn't mind very much. We let our enemies, actual enemies who abuse their own populations and want to destroy us and take everything in the world for themselves and abuse us too, use it against us. It's not free trade that's bad, it's the tyrants running these evil despotic regimes that we are too lazy and peaceful to do anything about. They lied to us and pretended that they were being reasonably democratic and we knew they were sort of lying but we gave them a passing grade anyway and let them carry on. Nobody minds that they torture their own people or work them to death when they're importing their nice cheap goods at a great price.

It seems like we hoped that if we provided them a good economy, freedom would follow. But that's putting the cart before the horse. Freedom must come first, then economy can follow. By tolerating evil, by letting free trade support and provide for that evil, we allowed that evil to infect us and now we're feeling the pain of what evil left unchecked will do to the world.

So now it's time to prepare for a war to defeat evil once again, because we let it happen.

Yeah, I have a feeling national security and a possible fascist takeover of the US wasn't their main bone to pick.
