Economics

We've spent the past week "Exploring Economics", and I think that we had some good discussions about entrepreneurship, supply and demand, scarcity, and globalization among other things.  This topic may seem unrelated to the ancient civilizations that we are studying, but we've actually been discussing economics since we did the "Road to Civilization" charts back in October. 

The start of agriculture led to a varied labor force (specialization), the build-up of capital (surplus), and all of this resulted in bartering for goods and services (trade).  Merchants and traders were the first entrepreneurs when they took the risk that their goods would actually allow them to trade for other goods of value.

We're starting the last section on Egypt soon, so let me ask you this - What kind of economic system did they have in ancient Egypt?  What evidence do you have to support your theory?
