Not defending PZ in any way, but ask yourself what you would do. Greed is a powerful human emotion.
This is all public information. PZ owns roughly 186,000 shares of AIG stock. In December 2019 the stock was trading around $50 a share. After billions of dollars of stock buy backs the stock is trading at around $63 a share today. If PZ owns 186,000 shares with more to come and the stock increased $13 a shares that equals $2,400,000.
Would you sacrifice thousands of employees for your personal gain? Stop! the easy answer is no of course I wouldn't, but could you somehow justify in your head that you are so important that you are worth it? I bet you could if given the opportunity.
Corporate America is broken.
