I remember visiting the stately home of Henry VIII. He was the richest man in the world in his time, but he had neither air conditioning nor indoor plumbing, no Tylenol nor a heated Shiatsu massaging chair.  We are all richer than the richest people of the world 75 years ago. What we take for granted today, kings and queens of Europe could not have envisioned. In fact, everyone reading this article is well within the top 10 percent of the richest people walking around the planet today. That means 90 percent of the world’s population think that if they had our money, they would have nothing to complain about.  So why don't we feel that rich?
