Wealth
When you do good, you can also earn benefits for yourself.
In December 2015, Business Insider magazine estimated Zuckerberg's personal wealth (including his shareholding in Facebook) at $46 billion. He made nearly $12 billion of that wealth in 2015 alone. As his salary from Facebook is just $1 a year, this increase was driven almost entirely by Facebook's rising share price, though he has made personal investments in companies such as Mastery Connect ($5 million), Alt School ($100 million), Vicarious ($52 million), and Panorama Education ($4 million), as well. Since 2010, Time magazine has declared him as one of the 100 wealthiest and most influential people in the world, and his income stream looks as though it will only increase in the coming years.
