Meeting the descendants after achieving that new status gave Khan a broader perspective on the amount of wealth they actually held. Calling them worlds apart almost didn't fit the description. No one could accumulate that sum in a single lifetime, especially without a background.
The situation appeared hopeless, but Khan could find a positive side. The reality check made him give up trying to match the descendants in that field. He would never achieve that, so he had to prioritize the only thing they lacked, which involved the Global Army.
