Schools also serve as “civic gyms” to train people so they can make sense of hyper-local matters—for example, air pollution, water pollution, noise levels, and so on. Because of this, people are able to train their “civic muscle” and become much more mature even before they turn 18. Furthermore, when the “Silvers” (the older generation) start training their civic muscle thanks to their grandchildren reminding them to participate, it is much more effective than the government telling seniors to participate. They tend to listen to their grandchildren.
