What's interesting in this debate is that Mark's own experience isn't where he puts his mouth. He spent the first 8 years of his career at Accenture (which screams failed attempt at making partner -- sorry to be harsh), but drastically changed occupations every two years inside the firm (switching from IT to strategy, changing countries etc.).
I really like reading Mark, so I'm afraid of overbearing my point. But his inital blog post sounded like shamelessly getting his cake and eating it too.
He felt that such frequent career changes were the best way to prepare himself to lead a startup someday -- why would the same trait magically become a liability in others? Optimizing against this very behavior in job selection signals a quite detrimental two-tiered mindset -- himself at the helm, and employees who are there to take orders.
This is to some extent the reality of capitalism, but it isn't admirable leadership, nor a good way to generate innovation, and certainly not the best way to inspire people to stick on a sinking ship while the rats drown away. As the OP said - money can't buy you love... :)
Contrast this with Yelp, Aardvark and the second-generation breed of entrepreneurs coming out of the PayPal and Google mafias.
