Completely agree with your analysis here mate, about that growth being unearned and in a sense unwarranted. Reckon my mum and dad’s house has increased in value about thirty fold since they bought it 45 years ago and my dad likes to take credit for that in a way that isn’t really justified. House prices have risen exponentially in that time, and he’s been a beneficiary of that, far more than it being down to any prescience on his part; although the house was pretty derelict when they bought it so maybe the true multiplier is about 20, but even so.
And actually my mum and dad are symptomatic of the problem. Two elderly people, clinging on to a house that is far too big for them, while their grandson, my son, cannot reasonably expect to buy a house until his thirties. I am grateful that they are both alive and healthy enough to live in a house together, but I personally wish it wasn’t that one. I feel it’s someone else’s turn, but it’s hard for humans to give up what they feel they’ve earned, even if the truth is that it’s mainly down to forces completely out of their control.
