Who is responsible for promoting the common welfare (good)?

Your local government helps take care of some of your needs in the community. The local pool that you may go to in the summer is provided and maintained by your city. The recreational center you play basketball or have soccer leagues in is provided by your local government. Children may be helped by the city providing day care facilities for the young people in your neighborhoods and communities. Senior citizens have centers and facilities that are often provided by the city. The local government provides public parking and public transportation such as busses or subways. There are many ways a local government can help promote the common welfare of its citizens.”
