Do you realize that you can make the same foolish statement about the US flag. There was far more slavery under the US flag than under the Confederate flag.
Yeppers, liberals use this red herring often. The slave trade ended in 1808, when there was far less slaves in the US than in 1860. The US flag is a flag that represented both demorat slavers and abolitionists until 1860, the rebel flag ONLY represented demorat slaver defenders.
Only demorats held that flag during the Civil War - not Republicans.
Stop defending demorat history.
I am not sure that is all together accurate. It wasn’t until the invention of the cotton gin and the subsequent boom in cotton production that slavery was even a successful economic model in almost any area of the country. It continued to be of little use in even much of the South. It was only really viable in the Deep South and the massive plantations that could produce large amounts of cash crops like cotton.
Without the Cotton Gin, a northerners invention, slavery would have probably been eliminated in the South as it had been in the North. It was the economic viability brought about by technological advancement that gave it longer life.
