On the house front - you wonder how much of an impact on being able to afford a house is caused by people spending money on other things e.g. the latest gadgets, the new car every couple of years, the 3 holidays a year.
This and the fact many people these days try to afford a house alone. Go back 30 years and almost everyone bought a house with a partner and not alone. And then didn't pay £1000 a year for communication products.
