I strongly feel this power, influence, giant houses, jets, personal cruise ships etc are old generation stuff - something that grey haired Gekko will personify. The "new rich" is dramatically different and for the better. Today's centi-millionairs wants to stay anonymous, don't want to have butlers, have houses that they can manage without permanent staff and often prefers travelling first class or renting Yatch instead of buying them even if they can afford it. The new rich sets target to make X amount of money and then "retire". Their "retirement" consist of working hard doing their favorite activities and travelling the globe to sample the "regular folks" flavors. Most of them don't have desire to keep growing billion dollar business which will sip away their time and energy. They have strong political belief but have no desire for acquiring political power directly or indirectly. They are not in to heavily influencing how rest of the population shall live. They consider time to do their favorite activities far more important than keeping money scoreboard. They want to buy fashionable cloths and accessories but not those that will immediately attract attention and single them out in the crowd. They want to be physically fit and avoid having family as long as possible. They like to invest in ideas and technology more than traditional financial instruments.
I think new rich crowd will almost completely replace old generation wealthy in next 50 years or so. People who are born in this decade will have very hard time understanding philosophies and life style choices of Gorden Gekko.
