Few years ago I was able to buy all I need to survive for €100 ($120) a week (rent not included). Today I at least need €200 ($240), although I mostly buy the same stuff as before. What do you think is the reason and what implication does it have long term?
Inflation is the most likely culprit, simply the value of money is not what it used to be. It is however not an even story because in some categories you have a deflationary cycle going on - where you are getting more for the same amount of money, think technoogy products etc, this manifests itself in things like a laptop or a phone remaining at a constant price with capacity and features increasing every year.
