I sense I am in the minority here, but I don't really care what he makes. CEOs for large public companies come with high price tags and are able to negotiate some serious compensation. Add to that the change in the price of AC stock over the last 10 years, or even just the last 2, and Calin has some pretty good leverage.
Not sure it's fair to assume he's giving the bare minimum to charity, or only what benefits him. There are a lot of people who give huge amounts of money to charity because they believe it he right thing to do.
