“Over at Snapchat, Mr. Spiegel, who is 23, apparently thought $3 billion was not enough for a company that, as yet, does not turn a dime of profit. But here’s another question: When is your number big enough? The most expensive homes in the Bay Area top out at around $30 million. Pick up a few fancy cars at $100,000 a pop. Throw in a Bentley for $175,000, a weekend place in Sonoma for $5 million, a modest pied-à-terre in Manhattan for around $5 million — fine, make it $10 million. And a top-of-the-line private jet for around $50 million. With expenses, taxes and what not, you’re barely past $100 million.”
