> Cotton was the US's #1 export from ~1800 through 1930 due to slavery

Wait, you're making a very different claim than what I was talking about. I agree that it probably made some sense to have some kind of plantation economy in the South, and that, as a matter of fact the plantations the South did have were based on enslaved labor. And for sure, there are interesting debates to have about the unacknowledged contribution that's inherent in that. But slavery was never a necessary part of that successful economy; indeed, it's quite physically possible to have plantations that employ free laborers as opposed to relying on slaves!
