You appear to be missing some basic info about Paddock. He was independently wealthy, having made a fortune in real estate.
He owned several homes, three airplanes, and was known as a high roller around the casinos.
I told you a billion times not to exaggerate: I have seen several reports that his net worth was in the $2 million range. That is not "independently wealthy," even without children. I have also read that he owned two airplanes, not three, but none since 2009 (repossessed?, and that he was a very low, high roller.
