If it weren't for his old man, he'd probably be dragging cables around on a movie set.
Actually, most entertainment and sports figures are far more successful than successful executives. Try managing a 100 million dollar career and you begin to see that each of these individuals is a business unto him or herself. As an example, for all the wealth that Michael Jordan has generated for himself, think about how much money he has been responsible for creating worldwide.
As far as old men giving a hand up to their sons, be careful where you throw that stone. Finally, any "successful executive" who casts his wife away, after she stood behind him and supported him for 30 years, to take up with a woman less than half his age can only be described with one word: scumbag.
Yeh, I wouldn't want to bean old Kirk. He's no saint, but I think he's earned some respect.
