Diesel Western Australia AUS$2.30/litre, approx US$6/gal.
It'll go to US$8/gal no problem. $10 or $12 or more won't surprise me and everthing will become as expensive as is necessary for people to beg for a government tit to suck on which will then be provided to them. Conditions and restrictions will apply.
I sleep in my truck or on a foam mattress on a suitably unoccupied building site, and come home every 5-10 days depending on work. I used to camp out anyway to save road time and money, so I'm accustomed to doing it rough, but current prices would mean spending $1000 a week on diesel. It'll soon be $1500 or $2000.
Color me foily but this is only just beginning imo. These prices will serve to disincentivise rural living in the short term and make it impossible for almost any working man by, oh say around 2030. 'Assistance programs' will be a necessity for almost everyone and will only be available in urban areas, conditional on doing whatever you're told while being perpetually surveilled. Rural infrastructure will cease to exist, food will not be available, and determined country bumpkins will get portrayed as a problem, selfishly gobbling up essential resources which are more efficiently used in high population density areas. The remaining non-elites who try to keep living outside permitted areas will be criminalized as planet destroying terrorists who are to blame for your child's malnutrition problems, and extreme measures will be justified and necessary.
Crazy talk? We'll see.
I will not be moving to an urban environment.
