Erik Dahlman, Chapter 11

I thought it was really interesting how people can game the system of different currencies not backed by intrinsic value to end up with huge profits. The fluxuation of the value of various currencies seems to suggest that there is large gaps where money is lost, which is where people can make money, meaning that we are losing money that could be spent other places within the economy. With this in mind, it appears that the economy would be much more healthy if the world were to have a common currency to prevent the "leakage" of money from the system in trading currencies.
