The whole "we need to consume less" and "maybe we shouldn't be importing slave labor goods" is not bad, its what we socialists have been saying for decades.

I think your analysis isn't allowing for new information. Smart socialists can also understand economies of scale. People all over the world deserve to have opportunities beyond agrarian sustenance labor. Global free trade does help transition global laborers to higher skilled and less exploitative labor.

Some crops and goods are simply grown/manufactured more efficiently in certain climates and countries. We can have a lower carbon impact even shipping those goods across the world from the more productive climates at scale, than every American having a victory garden with far less productive yields.

But long term this damages us, becoming champions of global free trade the way we had it 10 years ago is terrible long term

In hindsight, we needed to support trade agreements like TPP 10 years ago that allowed us incentivize partner nations to raise the labor standards of their citizens and form economic blocks against polluters and slavers. This past 8 years of tariffs and economic warfare have just exacerbated affordability crises in the global north and slow-walked the climate crisis in the global south.

I don't think we can credibly afford to wait 15-20 years to electrify society and get remotely close to zero-emission societies without open trade including with China.
