Looking at some examples, many billionaires are doubling their wealth every 10 years on inflation adjusted dollars. Some are obviously much less successful. But there is a good chance that small group of billionaire can turn in to trillionair in just a century. This amount of wealth is sort of a tipping point because it is enough wealth to outright buy a large portion of some region in a troubled country including autonomy that allows to establish a new country. Another alternative could be to use that amount of wealth to purchase politicians across the world and twist the laws according to one's dearly held ideology. Yet another option could be use wealth in major advancements such as building generational spaceships or curing long standing deceases. Depending on who those lucky billionaires are you could fair really well or get completely screwed, just like with monarchies. However even scarier thing is that in yet another century you could have people owning "petillionair" or 10^15 inflation adjusted dollars assuming they don't max out like in Moor's law due to upper ceiling on productivity of rest of the people. If exercised effectively by developing well disciplined army equipped with deadly weapons, this can actually bring back true monarchies and world conquerors with some rouge groups fighting against it. At this level of wealth, the desires won't be more wealth but more power. Hollywood was right all along :). Exponential laws are super interesting and this article has started lots of thoughts...
