I mentioned "Generation rent" only yesterday on MN ...
We are seeing the entire demography of the UK (and Western world) shifting under our feet.
There is already a generation that have accepted they will never own a house, with a second already forming - you read about it daily on Mumsnet. They are evolving into a new demographic which will bring challenges everywhere. At the most basic level, if you accept you are never going to own a house, you are never going to try and save for a deposit.
This is already happening - not some possible future.
Trying to cast the runes (what I am paid for) suggests that a rising swell of renters with "spare" cash that isn't earmarked for a deposit will find other areas to spend in.
Add to that "Generation can't drive" and it seems we will be living in interesting times.
One of the saddest factoids of the changes in society is that the first baby many people ever hold is their own - not sure why that upsets me so much ... at least I was able to hold my DB and cousins when they were tiny.
