Agreed. Rereading it, I now see how my statement about "using capitalism" sounds like I'm advocating maintaining it in some capacity. Poor phrasing on my part.

I meant simply that it's uncontroversial to recognise that we're living under capitalism presently, but that's just our starting position. That even if you think socialism or communism "needs capitalism" (debatable, academic), well that's step #1 out of the way already, because we've got it, so now what?
