Jeff Bezos’ Ex-Wife MacKenzie Is ‘Grateful’ as She Lands $36 Billion in Divorce from Amazon CEO MacKenzie revealed her decision in a letter posted to the initiative’s website. “I have no doubt that tremendous value comes when people act quickly on the impulse to give. No drive has more positive ripple effects than the desire to be of service,” she wrote in the letter. “We each come by the gifts we have to offer by an infinite series of influences and lucky breaks we can never fully understand. In addition to whatever assets life has nurtured in me, I have a disproportionate amount of money to share,” Bezos continued. “My approach to philanthropy will continue to be thoughtful. It will take time and effort and care. But I won’t wait. And I will keep at it until the safe is empty.” MacKenzie and Jeff Bezos.
