People keep saying Uber is burning cash, but their core business model is sound:

$5 per hour per driver goes to Uber

Assume 80,000 drivers (half of # U.S. Uber drivers) drive 8 hours a day, 7 days a week

52 weeks in a year

5x8x80000x7x52=$1,164,800,000

So about $1.1 billion just in the US. The only expenses are at headquarters (engineering, operations, design, legal, marketing, support) and the tiny field support offices they have in each city (local, entry-level employees).
