About your first point: a friend who joined in April 2009 and is now Engineering Manager says he stands to make about $10M if the valuation of $100B persists when he gets to sell.
I do often think about the non-monetary aspects of my life, and feel better knowing I'm not in terrible shape socially or financially. Thing may or may not have been similar on the non-financial front had I worked at FB - obviously, I'll never know.
