As the #population falls the number of #buyers will fall, and there will be relatively fewer buyers compared to each raw material. Consequently, the #price of raw materials will fall and everything built on that will fall with it.

It's not something I've ever read, but I've never read anything to contradict it either. The problem is, nothing is immune to this effect. Everything from #Oil to #BTC will lose some of its rarity as less people want them but the amount available stays the same.

It's the side of supply and demand that's never been tested. #Capitalism relies on #rarity to store #value. It's the elephant in the room.
