This is starting to get animated, I think muchmore context is required here.
In recent decades its true to say that living on council estates is seen as a second best option, and it seems that this view gets stronger as time goes on, and it is understandable to a great extent, but in those decades there has been a huge amount of political division at work.
If you look at UK history, throughout almost all of it, home ownership for the working classess has been very limited, and its only the last 40 years that it has been a practical reality, for many reasons from sheer poverty to lack of a decent banking system and insecuroty in employment.
The exemplar models of ‘public’ housing were largely put in place by industrial philanthropists such as Port Sunlight, Bournville, Saltaire - its worth looking these up if you want to have any understanding of social housing in the UK.
These gave a glimpse of what might be possible if workers were provided with decent housing - home ownership was simply out of the question.
The great obstacle to public housing was the use of taxes and city rates for housing, and the the landowners who argued for literally centuries that this would be unfair competition. Housing at the lower levels was often awful, and as the industrial revolution wore on it became much much worse.
It became apparent that the wealthy had plenty of interest in improving the lot of workers, especially in the 1830’s onwards when cholera came to Britain, especially in the great Victorian cities such as Manchester, Birmingham, Leeds, London.
The problem was what to do, certain studies were carried out that proved that communicable diseases struck more often and more intensely in the worst housing - usually having no connection to drainage, no water, not facilities, you can read all sorts of reports online about this.
The ‘Unhealthy Housing acts’ allowed local councils to declare housing unsafe according to certain criteria, but even so, it took decades vbefore they had the power of compulsory purchase before they could do much about it.
The demolition of unhealthy housing began in a wave around 1900-1910, maps were made in many cities which showed regions of unhelathy housing - all of which were then blighted and lost value - so the landlords didn’t maintain them even though it took decades more to actually do something with them.
These slum clearances seem to have been in waves, and in between not much.
The roots of true council housing began in the late 1920’s, these were built away from the crowded townships on virgin farmland. This actually excluded the poorest, as they could not afford the rents and the transport costs, so they were populated with the trade skilled workers, whose employment was often fairly secure and relatively well paid compared to the majority of the workforce.
British society was highly stratified, much more than nowadays and you would find that supervisors migh live in certain house that had perhaps a couple of bedrooms, and middle managers would live in slightly larger houses, you could readily tell the social standing of a person by the street they lived in.
These new council estates were seen as a social step up the ladder from the inner city back to back housing, there were tight rules in rent payment and maintenance of gardens - eviction was quite easy to enforce so people behaved themselves.
It was not all that long that the issue of people living in poor housing and low wages was recognised, and local authorities brought in a system of rent subsidisation for the low income workers. The skilled workers resented this, they saw themselves as earning their way out of poverty through self reliance, they set up tenants associations and during the 1930’s there were many rent strikes.
The differances and divisions were sert in, and after WW2 home ownership became the way out, skilled workers bought their own homes away from the council estates leaving the lower paid subsidised renters behind - it also started to create a self reinforcing social stigma.
During the 1960’s the pace of council estate building increased massively, but so did the process of skilled and better paid workers buying their own homes. Social legislation was introduced which compelled local authorities to house anyone in need no matter what their past. It also became very much harder to evict miscreants.
I actually remember people who moved into some new council houses being charged a slightly higher rent because of the view, you could be evicted for not keeping your garden under control - those rules were legislated out.
As the more motivated workers moved out, the rest were left behind, if you got a decent job, you moved out as soon as you could.
The best quality council houses were sold off to long standing tenants under changes during the reign of Thatcher who saw it as an opportunity to reduce the power of local councils and perhaps improve council estates, the idea is that if you own your own home you will take more care of it than if you are basicly given it.
This reduced the stock of council houses, and of course they were the worst ones too, such that the the only ones who lived int hem were seen as second rate by a large section of the UK public.
This has become self fullfilling, council estates often have a higher number of ‘undesirables’ who do not give one jot about their neighbours, they are benefit dependant and have a sense of entitlement yet they contirbute little of benefit to society - at least this is how many council estate residents are viewed by a goodly sized chunk of the UK public.
There is some truth in this but its really a stereotype, its not the whole picture. I can name some notorious council estates. In any case, just viewing them as social dumping grounds is unlikely to help the situation.
