The aim here is to try and help the reader understand the power of money and economics in modern history and politics.

Money runs a lot of things. Understand credit, understand the advantages of paper money, understand the role of money in realpolitik. These things must be learned about if you wish to understand your history, and modern politics. It's not for a joke that you can study history, politics and economics as a combined subject. Though I think economics should almost come first.

Woe to you who add house to house
and join field to field
till no space is left
and you live alone in the land.

Isaiah 5.8
