If one is going to claim that black children were better off in 1860 than in 2011, because they were "more likely to be raised by his mother and father in a two-parent household," then I need that person to explain precisely what he/she means. That is a claim made by a random Christianist group in Iowa in a pledge regarding heterosexual marriage (among other things, related to marriage and sex), that has been signed by GOP presidential contenders Michele Bachmann and Rick Santorum.
Unless I missed something in my academic training in American history, children in slavery could be, and were often, sold away from their parents at the whim of slaveholders. I don't think that "better off" even comes close. That pledge was likely put together in direct response to marriage equality coming to New York, as well as marriage equality in Iowa (and as far as I can tell the state has not descended into Hell fire), so why not just keep to the basic subject of fundamentalist Christianist understandings of marriage and sex (or the lack thereof), instead of wading even more unnecessarily into an area the group clearly knows little about.
