A friend of mine locally is worth a few billion dollars (my guess as we don't discuss those things). He collects EM's as well as new games. He also has some very cool, older PM machines (Pure Mechanical)
He plays regularly at home and also has machines available at his business for his employees to play. He and I have traveled to many pinball shows together and some of you have unknowingly stood in line next to him to play. He's unpretentious about his wealth unlike some upper middle class people that pretend to be rich.
Sensing the drift of this thread I will add this. He's not stupid with his money, he researches pinball prices, negotiate with sellers and will walk away from a pinball deal if its too expensive. He also repairs and shops out his own games.
Don't let television or the prevailing attitude towards rich people invade your consciousness too much. For a realistic view read the book, The Millionaire Next Door.
