Bloomberg:

Apple’s share price rose almost 5% last week, leaving the company Jobs co-founded 44 years ago in his parents’ California home on the cusp of stock-market milestone: a market value of nearly $2 trillion.

And:

It was valued at about $350 billion when Jobs died. Cook, meantime, has joined one of the most elite clubs for CEOs who didn’t actually found the companies they run: his net worth has eclipsed $1 billion, according to calculations by the Bloomberg Billionaires Index.

Reminds me of this: Name a billionaire who worked for another billionaire while both were billionaires. If you want to guess, reply to this tweet.
