Economics
To quote Wikipedia, "economics is the social science that analyzes the production, distribution, and consumption of goods and services."

Economics and politics go hand in hand. Think "money & power". Economics is the "money" and politics is the "power". Politics deals with the making, interpreting, and enforcement of the laws of a society, while economics deals with the creation and distribution of resources in that society. To make it even clearer, we can even say "economics = resources" and "power = influence". Money and power go together so well because I'm sure you can imagine people using resources to gain influence over people, or people using their influence over people to get money.

It's no coincidence that the wealthy members of society also happen to be well connected politically. Or why the people the people in office mysteriously find their personal fortunes and investments increasing. This is why incredibly wealthy people will take drastic pay cuts in order to run for political office- because then they'll be able to shape the very rules of the society they live in (or do business in). This is literally how the rich get richer and the poor get poorer, and the way the ruling elite clings to their wealth and positions in society. As I said before, it's all about money and power.

Needless to say, this section will break down and explain the basics of economics. Some of the terms in this section could also be added in the "Politics" section, while some of the terms in that section could also be added here, since you can't have some without the others. Ok ok ok, technically you can have each of these systems isolated in theory, but you'll virtually never find them isolated in reality.

Another note, as with politics, history and health, the field of economics is huge! It would be impossible for me to break everything down about it, so I won't even try to do that. What I will do, however, is introduce you to the basics & tell you the truth, however complicated or unlikely it may seem. And with this as your foundation, I believe you'll be able to understand politics and business far better, as well as understand the world of men to a much higher degree.

Also, for the record, the two links to the right listing the net worths of our Congressmen are flawed. This is because they don't include the net worths of the husbands or wives of each person, For example, John Kerry's wife is worth at least $1 billion (according to Forbes Magazine in 2008) and John McCain's wife is easily worth more than $100 million.
