I doubt that there will be that much variation since even if you look at it, you are considering a sale of assets or a purchase. There are thousands of such transactions happening everyday. That range of fluctuations doesn't happen. I'm not great fan of central planning, but I think that NGDP or nominal wage targets are possible to hit without a 100% variation.
The last thread didn't fare too badly, I think; let's make it a monthly tradition. (Me, I'm more interested in thinking about real-world policies or philosophies, actual and possible, rather than AI design or physics, and I suspect that many fine, non-mind-killed folks reading LW also are - but might be ashamed to admit it!)

Let's try to stick to those rules - and maybe make some more if sorely needed.
Oh, and I think that the "Personal is Political" stuff like gender relations, etc also belongs here.
