In the US I see a lot of household costs that are going up above and beyond inflation especially in California:

* Transportation (No good public transit or usable bike infrastructure so stuck with Cars)

  * Registration Fees

  * Toll costs

  * Gas Taxes

* Power - Electricity costs are going up, especially in CA

* Water/Sewer - Getting more expensive, especially in CA

* Trash - Waste Management is taking over and gouging prices like crazy

* Housing prices near workplaces are skyrocketing requiring ultra-commutes increasing transportation costs

I was pretty much priced out of California... That place is going downhill fast affordability wise. Unless you have a VERY well paying job it's barely livable.
