We have planning at the county level. All that does is place power in the hands of the powerful realtor/developer group.
As a result, local imbalances abound. If you live in an area where those sorts of folks also live, it's really nice. If not, you get prison, dumps, subsidized housing, etc built right next to you.
I can only imagine what this would look like if this was done at the state level. Our state is solidly one party...
