all the world's a pyramid scheme...

"pyramid schemes, chain letters and Ponzi schemes

A pyramid scheme is a fraudulent system of making money which requires an endless stream of recruits for success. Recruits (a) give money to recruiters and (b) enlist fresh recruits to give them money.
A pyramid scheme is called a pyramid scheme because of the shape of a pyramid: a three dimensional triangle. If a pyramid were started by a human being at the top with just 10 people beneath him, and 100 beneath them, and 1000 beneath them, etc., the pyramid would involve everyone on earth in just ten layers of people with one con man on top. The human pyramid would be about 60 feet high and the bottom layer would have more than 4.5 billion people!
A diagram might help see this:
1
10
100
1,000
10,000
100,000
1,000,000
10,000,000
100,000,000
1,000,000,000
10,000,000,000
Thus, in very short order, 10 recruiting 10 and so on would reach 10 billion, well in excess of the earth's population. If the entire population of earth were 5 billion and we all got involved in a pyramid scheme, the bottom layer would consist of about 90 percent of the planet, i.e., about 4.5 billion people. Thus, for 500 million people to be WINNERS, 4.5 billion must be LOSERS."

In other words, the first world is ripping off the the third world in a scam widely recognised as being completely immoral and unjust.
