I've been working on some economic models for political topics. If we pay for political power in terms of liberty, in a fashion that mirrors supply and demand of goods, then I think that type of model could be a fruitful way of understanding the way people think, politically. I've included a drawn model representing this Supply and Demand of Liberty below, in reference to people's Demand for and the government's Supply of Security. This applies to more than just Security, but that seems to be the hot button excuse whenever most political actions are taken (that's why "Think of the children" is a popular phrase when politicians have something they want to get pushed through).
Let me know your thoughts, and I will go into more detail on this in a future podcast episode.
