Sidewalks were invented in big cities in the 1800s as a way of separating people from the filth of streets. They found a second use in the 20th century as a way of separating pedestrians from automobiles. After World War II, sidewalks declined in popularity, only to rise again in recent decades along with urban trails. Throughout, governments have been the key to pedestrian access.
Farmers markets have caught on in big cities since the 1970s, and a major reason is that governments have subsidized and facilitated their growth. Why? Because farmers markets create “positive externalities,” benefits that are much greater than their costs. They bring neighborhoods together, improve health, and make city life more affordable and enjoyable. And they’re another way government improves our lives.
Building codes show us how governments make our lives safer while reducing costs for everyone. They do so one construction project or remodeling at a time, so their impact is nearly invisible. Until, that is, you look at statistics on fire safety, energy usage, or water consumption over time, where you can see that government has made enormous progress but done it quietly, steadfastly, at scale, and often in collaborative ways.
Public transit didn’t start out as a government service. For more than a century, it was a for-profit industry that government assisted and regulated. When ridership declined and corporations abandoned the business, governments stepped in to keep transit alive. Why? Because buses and trains help cities work better. They also make urban life more affordable and appealing.
