they allocated their fortune because they basically took over the controll of all major high developed national currency central banks,

they have a complicated family system which is like a iceshelv with a huge underground unknown part,

of course its easy to do a fortune this way, they are not forced to sell their time like ordinary citizens, they simply create money and look for desperate idiots that sell them their time, this way they allocate passive income sources that are stable, and get richer and richer, while the 99% is desperately selling their time.
