Suppose you and a few of your very rich firends took a look at the world and saw that there were two big problems.
First was world population growth, and second was the rise of a middle class in many countries where no middle class had existed before.
The combination of the two factors indicated a serious environmental catastrophe was about to happen.
They pondered how to stop the inpending disaster, and they came up with a simple plan.
In essence, the plan was to destroy the middle class.
Take away the social safety nets, render the public school systems ineffective, disenfranchise as many voters as possible, and make the tax structure regressive so that upward economic mobility is stifled.
