The fact that we have a finite amount of time to use doesn’t mean that we should waste it by using it up. Instead of buying a disposable phone, I buy my own. At a time when I can’t afford to pay for a new phone, I can use the subway to purchase a few minutes of my own time.

We’re not talking about a phone here. We’re talking about the New York City subway system. The subway system is a system of track operated by the subway, and it provides service to all of New York City. It’s designed to handle the time it takes to move from one location to another, but also to be a convenient way for people to get around town easily.
