Since the part M building regulations in 1970, buildings have needed to be physically accessible, especially after the 1995 Disability Discrimination Act. You can therefore argue that over the last 40 years that accessibility have been a key component of the investment made by all sectors and this can not be ignored.
In terms of physical access, we do live to the most part in the social model world disabled people fought for. The country is more accessible and we should have disabled people being more positive and using what society has given them. If some disabled people are still complaining about barriers as a reason to stay at home and do nothing, society has wasted money providing something that was not wanted.
We must respect what we have achieved and not just take it for granted, claiming nothing has changed,
