One of the big problems with living in rough parts of major cities is that it often takes a long time for the police to respond to emergency calls. A company called BlueLight wants to improve that situation, for a price: “The service cost $20 a year and promises users that when they dial 911 from anywhere in Oakland, the Oakland Police Department will have access to their exact geographic location.” At first glance, this service seems to provide the perfect illustration of the growing technology gap. But it’s more than that. It’s a stark reminder that the inequality gap impacts almost every aspect of personal health and safety. From better food to concierge medicine to home security systems to safer cars, it really does pay to have money. And if you expect something as basic as equal access to first responders, well, there’s a gap for that.
