Articles on this subject rarely seem to discuss it, but I sometimes wonder to what extent the growth in the number of millionaires is attributable to the huge worldwide growth in regular national/state lotteries which so regularly give multiple millions as their jackpot prizes. It may not be their intention, but they're certainly a way of "taxing" the many to concentrate wealth in the hands of the few. (Obviously I don't mean "taxing" literally.)
I doubt it. It's got more to do with inflation and wealth creation that happens everyday and is accelerating in the developing world.
