Here’s the scenario: A man and his wife are desperate to get to the hospital because she is about to deliver a baby. It’s a hot summer day. It’s rush hour.

So, is this a story about a cabbie taking advantage of a vulnerable couple or is it simply good economics? Today, we are talking about a company that charges people in desperate situations more for a ride, and we’ll consider the argument that it might actually be better for everyone.
