Isn't that... good? What else would be expected if you have a disability, and need accomodations?
Offering accommodations to people with disabilities is good. So you do that.
Then you recognize that not all disabilities that deserve accommodations are obvious so you establish some bureaucratic process that can certify people with these unobvious disabilities so they can receive the accommodations you meant for them to.
But the people you delegate to issue those certificates are... well, they're people. Some of them are not so discerning, some of them are not so bright, some of take pleasure in gaming the system or playing Robin Hood, some of them accept bribes and trade favors, some of them are averse to conflict.
Next thing you know, you've got a lot of people with certificates saying that they have unobvious disabilities that grant them accommodations. Like, way more than you would have expected and some whose certified disabilities are really unobvious.
Might the genuinely good system you put in place have been abused? How can you know? What can you do? And if it's not been gamed, then what the heck is going on that sooooo many people are disabled? That seems like it would reflect some kind of social crisis itself.
The system's resistance to abuse is one of its important characteristics. So if the system have been abused on that scale, the system probably wasn't good in the first place.
