Because NOBODY else can do that job like he does. Open market. Don't pay him, he goes somewhere else with his unique skill and leadership set. Just like the Weston family etc will with their skill and capital.
Would an editor please explain to Doug how the economy works? The capital of any family, rich or poor, is made available through deposits and investments to those who can make a convincing case for its more productive use. This allows others to enrich their families. 
Just think Doug, if you had chosen finance instead of journalism you might be able to access some of that potential wealth generation - available to us all. YOUR choice in our great country.
Nobody has commented on how some of these multi gen wealthy families have enriched our lives with cultural, hospital gifts etc that are staggeringly generous. No naïveté, these are generally deductible, but would never happen without the embedded vision.
