There's a new wave of segmentation starting up in Georgia and likely moving to other southern states where counties providing services to large unincorporated areas are still the order of the day.
In other parts of the country, New England, the upper MidWest and the Western states, unincorporated territory has virtually disappeared as the landscape has been carved up into cities, also known as municipalities. Georgia has 159 counties serving about ten million people. So, you might think that, whether they are full-service or partial-service counties, the jurisdiction should be small and compact enough to do a credible job.
But, size doesn't seem to have much to do with the level of service. The proponents of setting up new municipal jurisdictions in Georgia quite frankly admit, as you'll see in the following video, that the segmentation and re-organization is largely motivated by money, nepotism and entrenched customs. So, in a sense, it's a divide to conquer strategy, even though co-operation is called for. Co-operation, we might note, is also what Congress claims to want from the President of the USA.
