This happens to be something I believe strongly, but the comment you're responding to doesn't make sense even if you strongly disagree with that, as it supposes we can snapshot American society as it is in 2016 and synthesize from it reliably just and sensible decisions. Nobody believes this, no matter what their politics (unless there's a "status-quo-ism" I'm unaware of).
The problem (or at least, one of the more important problems) being addressed in this work is the unintended amplification of the status quo --- the implicit notion that if something is a certain way now, it is best that it always be that way.
