123coco mentions Thatcher. Thatcher, who decades ago decided we all should aspire to home ownership - whatever our circumstances - and buy our council houses at knockdown prices, while councils themselves had their power to build taken away from them. That meant fewer affordable houses available for families to rent - and more families in need placed in flats in tower blocks, which were known to be unsuitable. Since the 1980's many thousands of houses should have been built every year to replace the ones lost this way, and to meet newly identified need. They were not.
Now we are all suffering the far reaching consequences of the political and economic decisions made by those in power. We should not be blaming each other for the lack of choices available.
I myself now live in a what is known as a mixed tenure area. I own my house - which, yes, is now too big for me - but am in a low income area with few permanent jobs. In common with many others in the area, the house remains unsold. For the time being my disabilities are minor, and I am managing with occasional paid help cleaning and gardening. Eventually, no doubt,should I survive into old age, I will become a danger to myself. The local authority will be able to force me out and into residential care, sell my house (again at a knockdown price) and use the money from the house I worked hard for all my adult life to pay for my care.
Many people would be prepared to move from their homes if they could find a suitable property in their neighbourhood. It matters that you do not have to move miles away from the friends and support systems you have built up over many years, and which become even more important in older age. You are less of a cost to society, too, if you have these systems to rely on; especially if you have no family close by.
But bungalows everywhere are scarce - and so are at a premium. And in our rural area there are few flats and no tower blocks.
