Wealth typically only lasts 2-3 generations. That might change as people have fewer kids. Takes 2-5 generations to go from poverty to top 1%. I would give cita

  Your phrasing is a bit misleading, wealth is very fleeting, but the 2-5 generations to get into the top 1% is not "typical" by definition 1% of people reside in the top 1% - if we were to assume that the cycle of boom and bust is the lower bound in your example (two to fall out, two to get in) then one out of every five generations a family should be in the 1%, yielding that 20% of the population should currently be in the top 1% - using your upper bounds it's a bit less silly but still mathematically unsound _and_ I would strongly challenge that 2-3 generations number. Evidence that I've seen doesn't support wealthy families falling out in 2-3 generations (except borderline wealthy families) and the dynamics of money are changing, the estate tax has been abolished and we simply don't have enough information past 1980 to see if that claim will hold true... and what evidence we have (general information about wealth inequality) is showing a strong trend to continue the concentration of wealth.
