The best way to describe Zuckerberg's current lifestyle is
altruistic. Most of that can probably be credited to his wife, who is a pediatrician and one half (arguably the most important half) of the Chan Zuckerberg Initiative. Together they've pledged 99% of their Facebook shares (that means 99% of their wealth) to the organization, which focuses on "promoting equality" and "advancing human potential" and has so far done everything from helping to train developers in east African countries and launching a program to cure childhood disease.
