Funny you mention that because if you go back to what slave owners wrote back then you'd notice that they became very excited in 1840s after Karl Marx published Communist Manifesto. They used those ideas to defend and justify slavery. Capitalism is FREE markets and people making FREE choices. Marxists do not like that. They like the State choosing for people and the State providing for people. Slave owners saw themselves as the "providers" for their slaves who were too incompetent to provide for themselves (in the view of the owners).
