Why are so many employers unwilling to accomodate for people with disabilities?

Noise sensitivity, slight learning disabilities, somewhat longer breaks now and then for sensory sensitive people, wheelchair ramps and wide enough elevators, and cracking down on workplace bullying. We could make a long list here. These are not huuuuge changes. It seems more like the exception than the norm for accomodations when there are many that could work somewhat to working well if they got some (or got employment in the first place).... Not to mention being unemployed which is statistically more likely for disabled people will make you look bad to recruiters. Check the unemployment stats in the UK for disabled people. It's comical how unwilling people (and society of which we live in) are to adapt and change a little bit for disabled people.
