There’s a difference between having children and leaving a dynasty behind. At his advanced age, a man leaving a dynasty behind would have already passed the torch to his children and worked in the background to build and solidify their power. Luckily for us I don’t see any of his children being power players on the world stage like George is. The Rothschild family, on the other hand, has been building their dynasty for several hundred years and are doing an excellent job at it.
take a look (you can see the line-up at the top and each is clickable):
I’d say they are well-positioned for the future. He procreated later in life. Rothschilds have had centuries. George is 1st generation. In 60 years, there will be a dynasty of 3-4-5 generations and counting. In the future, they will populate education, commerce (Uncle already controls ports and shipments), media/arts and investment banking. Probably politics, too, in some capacity. Thankfully, I’ll be long gone.
