@DavBot @rbreich It's not about profits. It's about value. You don't become a billionaire by earning money, you become a billionaire by increasing value.

Unlike Smaug, Billionaires don't hoard gold in a cave, they hoard numbers on the spreadsheet. Billionare is basically an accounting term. A person who holds at least billion dollars worth of assets. Musk is billionaire because he owns large enough portion of $500 billion company. And he got that portion by buying it when Tesla was valued in millions. It's just numbers in database that have value because people believe they have value. On the other hand, so is money in the bank.
