Economic systems impacting today.

Trade and commerce have greatly impacted how the modern wold is today. We might not have the same ways of trading and not neccisarly the same things being traded. But the concepts that have evolved from trade are still being used today. We still trade with other countries for their resources and other goods.

Another thing that is still impacting in modern society is the trade centers. Now large cities today  have all evolved from small places of trade.
