> No one says disabled people cannot attend elite universities

The author spent the byline and first half of the article trying to explain that these universities wouldn't accept people with disabilities because they're just too elite and highly-selective. The recent surge of disabilities is actually perfectly explained, even in the article. The diagnostic criteria for disabilities has changed over time, becoming more "relaxed" as some would put it. If the diagnostic criteria expands to include more people, we are going to see higher rates of disability.
