*(This is question #2 (of 3), about the same text that I quote in this question).*

Question: what does the "pour ça" mean in the text below? I cannot figure it out at all. If I attempt to translate the sentence that the "pour ça" is in, I end up having to completely ignore the "pour ça".

If I try to articulate my confusion:

* I don't know what the "ça" is referring to
* I don't know how "for that" relates to the rest of the sentence, in "Is there a kind of happy medium that we could move towards **'for that'** ". Does "for that" mean "for the sake of that", perhaps? Or perhaps "in order to accomplish that"?
* What is "for that" attached to: eg, is it attached to "happy medium" ("happy medium for that") or is it attached to "move towards" ("move towards for that")?
