I'm fascinated by people like this. Why would you give up the ability to have uninterrupted interactions with family and friends in exchange for running Walmart? I know the answer is money but I would assume that, at a certain point, you have more than enough money to do literally anything you want in the little bit of time you leave yourself to not be working.

I would understand if she was running a huge charity; she would feel that interrupting family time is a sacrifice she makes to improve the world. But, Walmart is just a mechanism to extract value from customers.
