One reason for inflation is the demand/supply ratio: the more demand, the less supply, the more prices rise.
Another reason for inflation is technological improvement. I'm not talking about electronics, I mean mechanical technology.
Way back when cars were cvars, not computers on wheels, the newer model would often have a fancier paint job and chrome hubcaps, yet cost a tad more. And overall prices would rise.
See the cost of a Chevy BelAir from 1954 to 1958, I don't see a technological improvement yet prices rose.
A third reason for inflation is monetary devaluation, so that imported goods will cost more because on the foreign exchange you need more Dollars to the Yen or DMark or whatever.

When it starts approaching that price here,.. it won't be the end of everything... but, it will stop the size war on the streets...
We'll start driving cars instead of tanks...
Gas here in Italy is currently €1.80 which means $9.40/gal.
Even back in the 1970's, we only needed a 1.3 liter engine to develop 100hp, and a 2.0 liter car to develop 150hp. (Alfa Romeo figures, SAE net)

It won't,.. because there would be massive outrage if the price suddenly jumped to $7 or $8 a gallon...

It seems odd to be able to afford these unnecessary luxury items, but be cold and eating food that is discounted...
Luxury is cheap... life is expensive...
Seems out of balance...

Milk, bread and flour are three subsidized necessities wherever you go.
Luxury is cheap only in those nations where immediate pleasure is considered more important than the bare necessities.
See Aesop's "The Ant and the Grasshopper".
As far as I am concerned, the only debt I have is my mortgage, which will expire in Dec.2016.
Everything else is bought and paid for upfront. If I can afford it, I buy it, else, I leave it on the shelf.
PS I buy milk, fresh, one quart at a time, on a daily basis; same for bread, fruit, vegetables.
It's the "Old World" habit of having produce grown and sold locally, as opposed to the settler habit of riding to the PX once in a while and loading their wagon.
