There isn't a more destructive combination than "Greed" and "Ignorance".

Either one, taken on it's own can lead to any number of possibilities.

The accumulation of wealth and property aren't necessarily bad. Good or bad is determined by the way wealth and property are used. I admit this is a definition of greed that omits the "selfish" aspect. But Greedy people in history have provided the means for other people to earn a living that they might not have had.

Rockefeller comes to mind.

To some, ignorance is preferable to an awareness of things they can't confront or don't feel they can change. And in some cases, peole have accomplished great things, simply because they didn't know that ,"You can't do that."

Bu when you put the 2 together, the results are almost always predictable.
