Bottom line is I didn't return to Apple to make a fortune. I've been very lucky in my life and already have one. When I was 25 my net worth was $100 million or so. I decided then that I wasn't going to let it ruin my life. There's no way you could ever spend it all and I don't view wealth as something that validates my intelligence.
It is one of the issues that will have to be worked through however let me make the point and I think anyone would accept that if you set it up properly not only will you get better environmental outcomes you have a chance to create more wealth with the available resource.
