The reason why disability discrimination never stops is very obvious.
Because disability discrimination is not a criminal offence and not a few disabled persons can afford a lawyer to file civil cases against perpetrators, members of institutions – particularly faculty staff within universities – are free to mistreat the disabled, ruin their lives or even make them kill themselves without repercussions.
University administrators, who manage internal complaints procedures, are more likely to protect abusive faculty staff than vulnerable disabled students because the former publish papers and boost their rankings while disabled students are deemed a replaceable source of income.
Disabled students are more likely to fail out due to ill-health and lack of reasonable adjustments, which often exist on paperwork but can hardly be enforced since not following them is not a criminal offence for those faculty staff, not mentioning that it is prohibitively expensive, extremely difficult and unusually time-consuming to get legal representation for such cases – most lawyers don't take them pro bono.
Any formal processes are taxing for disabled students, which cause most of them to choose to put up with predatory harassment and career destruction by faculty staff, resulting in the encouragement of disability discrimination having ruined the lives of millions upon millions – made worse by the current importance of diplomas as a job entry requirement.
Simple questions: Do you find more faculty staff committing corruption than disability discrimination? Do you find fewer disabled people living in poverty than prosperity?
The answers are obvious.
So long as disability discrimination is not a criminal offence, this problem can never be resolved.
