Except that at those times, you could absolutely compare slave economies to non slave economies, and the non slave economies were healthier

It's why during the civil war, the north was so much more powerful than the south

Turns out that if you stifle the potential of half your population, lock them in bondage, and assign a significant portion of the rest to watching them, it's not very efficient. It's better to just pay people, even discarding the abominable immorality of slavery and focusing on just economic efficiencies.

"it's slavery when I work for money" ok clown

Liberals: this is a difficult situation and it's not one which has an easy solution

Communists: genocide is an easy solution lol

Capitalism is the worst way to run an economy. Except, of course, all other ways which have been tried.

Launching rockets at civilians isn't glorious whether you're Russian or Palestinian.
