There are many legends surrounding the search for the Holy Grail with Chrétien de Troyes Arthurian anecdote being probably the most recognizable. According to the story Arthur’s knights searched for many years before Perceval found it at the abode of the Fisher King.
A few more tidbits of information, at last count there were more than 11 million households with an annual income of one to nine million dollars. The ultra-affluent (defined as an annual income of over nine million) who also fit the demographic profile spend even more extravagantly. Some examples of their spending habits are that they spend on an average annual basis 30k on wine, 200k on jewelry, and 250k on clothes.
The facts are that there is a huge untapped market of new affluent owners. They have the money, they fit the demographic profile so why aren’t they owners? Perhaps those charged with finding them don't know where to look or how to attract them.
