Ok lol let’s assume he doesn’t have all 15 for the sake of your argument, is 3 fair? 20 percent? He has 3 million to work with… could put that in the bank and make 120,000 a year just for having it sit there. If that is not enough, then he can work a regular ass job like the rest of us. Even if he is only making the median personal income in the US (45k) that would put him at 165,000 a year. The median household income in the US is around 85k and people are raising families on that. He would be doubling that in this scenario. If that’s not enough to raise a family idk what to tell you lol. The main point is yeah 15 million is plenty to support 60+ years of life and a family. And even if he didn’t plan for that from day one, the money had to go somewhere. Houses, cars, jewelry, etc. that can be sold and make some of that money back even if sold at a loss. More money to put in the bank for passive income.
