The focus on IT in the article is inevitable ( this is El Reg after all) but it's too narrow.
Middle class aspiration ( and schools themselves perhaps) is to aim for traditional subjects and professions.
Vocational and professional degrees ( or A levels) other than law/medicine/accountancy are seen as being second best choices. Often at new universities rather then Russel Group ones, or poor relations within them.
It's not a new thing either.
Thirty odd years ago I did my PGCE at a very well regarded education department in a mid-range uni. Education students were crammed into an old house away from the campus. We had ancient equipment, tiny library etc.
The mediocre law and medicine departments had premises and equipment we could only dream about.
