Skeptic but Jewish Capitalism Ended Slavery
It does not make sense to say that capitalism was responsible for slavery when slavery existed under any system. Indeed, it is possible to make slavery compatible with any system by declaring that the slave class is simply sub-human. These socialists that attack capitalism on the slavery issue fail to realize that in a socialist country the same exact problem can still be present if the state declares a class of people to be slaves. Indeed, this is exactly what happened with Nazi Germany, if you want an example. Nazi Germany was a socialistic country that forced Jews and other groups of people into labor camps to do work for them. That is slavery and it happened under socialism. So other systems also are not immune to practicing slavery.
Therefore, the argument that capitalism was responsible for slavery is a false-cause fallacy. The fallacy arises because one confuses capitalism, a factor with slavery, as being the cause for slavery itself. Not to mention that this is a bad causation to draw from capitalism considering that it correlates with about 7% of all slave history.
My argument is that the opposite is true. It is not that capitalism causes slavery it is rather that capitalism ended slavery. Ever since capitalism appeared as an economic system something interesting begins to happen. Slavery becomes less and less practiced globally. Up to most history slavery was the common institution. Then capitalism becomes more accepted, and when that happens, slavery slowly begins to disappear. So I see capitalism as the liberator of slavery than the other way around as what other people suggest.
"It is a common criticism of capitalism, in places like college, to condemn capitalism for being pro-slavery. The argument is that slaves were traded on the market back and forth for the sake of earning profit. And so it was capitalism that was responsible for the evils of slavery."
In the US, it was the evil of chattel slavery that was responsible for the success of capitalism, and only the chattering class on the Right are surprised slavery carried within itself the seeds of its own destruction.
