Political Public Service
What would be incentivized if politicians were only allowed to work in the public sector after office? Instead of sitting on the boards of defense contractors or telecom giants, they could only serve as a teacher, firefighter, doctor, public defender, etc.? One would hope this would ingrain the notion of public service in politics; once you cross this threshold, you are committing to a life of public service, of bettering humanity for the long haul. There are certainly negative implications for such a rule, but outside-the-box thought experiments can be useful to spur innovation of our political systems, which obviously require reform. We can do this if we keep working at it. We can change the world.
