I read somewhere several years ago that Musk promised the UN that if they brought him a workable way to end childhood hunger for $2 billion or less, he would pay for it. They did, he didn't. When you grow up wealthy under apartheid it's difficult to give a damn how long and hard your employees labor to keep you rich because, after all, you deserve to be rich while the others are mere labor to build more of what you believe you deserve- for yourself..
