Having more government involved in any part of this won't fix anything. People need to want to be in more rural areas. Making grads be in a certain place for x years, meeting specific quotas, making new laws, etc will only have the opposite effect. Less government, less taxes, less regulation fixes all things. When the free market can decide where, when, how, and how much then things society will find a way to make it work. Government creating artificial scenarios never works.
