Slavery, capitalism, socialism and freedom

A video of Vice President Mike Pence declaring that "Freedom, not socialism, ended slavery" appeared in a Facebook friend's post recently. I did not watch the video. I'm trying to preserve as much of my sanity as possible. But it got me thinking about how the words slavery, capitalism, socialism, and freedom, are currently understood in our society. Or should I say "misunderstood." I would challenge Mr. Pence's assertion that "freedom" ended slavery. Freedom was the result of ending slavery, not the means for ending it.
But I would go further to point out that a civil war ended slavery. And the American Civil War was, by its very nature, a socialist endeavor: created (declared), financed, and run by the collective we call "government."
On the other hand, capitalism ("freedom" to the GOP) was the soil from which slavery sprang: profit as a primary motive, and cheap resources as a primary means. Capitalism is, by its nature, amoral (different from immoral). Unchecked capitalism will always lead to things like slavery and authoritarianism. In fact, our current capitalist economy depends on relative slavery, in the proliferation of sub-living wage jobs. And it was only recently that the US recognized slavery happening within its own territory of the Northern Mariana Islands. This was not just recently discovered, however. Do a search for "Tom DeLay Mariana Island sweatshop factory" to learn more. At a party with sweatshop factory owners there, Congressman DeLay declared "You represent everything that is good about what we are trying to do in America." Republican congressman, I should note, a member of the party of "freedom through capitalism" - which for me always begs the question of "Freedom for whom?"
Both capitalism and socialism are amoral - without any awareness of good or bad. They are systems in the same way that a shark is an "eating machine" (Jaws, 1975). They do what they do. And they each require vigilance, which means regulation and enforcement, to work for the good of society.
So, no, Mr. Pence. Capitalism is not the same as freedom. And neither capitalism nor freedom ended slavery in the US. Because it was a socialist effort that freed the Southern plantation slaves.  And because slavery, in one form or another, is with us still.
