And then you get a lot of cultural diffusion. The Middle East, which now is maybe known today as some parts being lacking in cultural diffusion, had a lot of cultural diffusion back then because the trade routes would take Arab traders throughout, you know, the world and expose them to different music and art and ideas and they would bring them back to their communities. So basically we're starting to push from traditional to market because of that idea of scarcity. You know, the Middle East was first in this world because in Europe at the same time we're in the Dark Ages. You don't have a lot of trade in the Dark Ages to the Crusades really. So really you have a feudal system. And the feudal system is more like the traditional model.
