That's the opposite of the right wing, which supports road and fuel subsidies and zoning and density limits [baconsrebellion.com] that force people to drive more.
Or.. you know.. get a job closer to home?
I'm not sure having thousands of people crammed per square mile is a great idea.
I think less dense housing enables people to actually do things with land, like, I don't know, grow a small set of crops?
Local production and consumption is a win on energy losses through transportation.
City people often forget that it is the country that feeds them. When you are that sheltered from production you tend to think food just magically appears in shopping centres. Sure, you know that at some point that it came from a farm, but it doesn't cross peoples minds.
Shoving more and more people into dense cities is not sustainable. It seems to be a goal of the left to see how many people we can support even at cost of quality of life. Screw that, Let people live in open areas, and let them have some level of being able to do what they want with their land.
