It doesn't do that though?
The civic reduces pop consumer goods consumption, and the Rangers from the Ranger Lodge Holding do too, but that's it. The normal building doesn't reduce consumer goods consumption in any way.
You are right. What I meant is that the ranger's consumer goods reduction seems like the building's main appeal (create ranger jobs so your planet pops have less maintenance), with unity generation being a weaker, almost negligible bonus. That's why I suggested that perhaps the building should double down on this, and add additional discounts to consumer good consumption.
