Any spot on the political spectrum has room on the left and the right. The goal should be to move the midpoint.
No, one size doesn't fit all. People that live in cities own very little personally and live a communal lifestyle where most property is shared. There are many rules to follow, few freedoms allowed, and a heavy handed and expensive government is required to make it work. There are too many crazy people in close proximity for gun ownership. In the countryside it is all the reverse. They don't need big expensive government and don't want it.
An economies of scale graph is a curve rather than a straight line. Currently cities are much more expensive to live in indicating they are well past the peak of maximum economy. The peak of the curve is currently somewhere in the suburbs. New technologies such as computers/internet/cell phones/self-driving cars/robotics, all falling in price about 10% per year, are pushing the peak towards the exburbs.
We need to move away from middle-of-the-road one-size-fits-all solutions. It is bad government at its worst. What works in the city communes does not make any sense for people that live in normal America.
