That's not quite what your earlier post said, however - you implied that law and education now attracted graduates of a lower calibre and that other professions had supplanted them.
But I do think this is true a bit. Back 30 years ago when 15% of people went to university, a lot of them would have done law, medicine, teaching.
Now, more people go, and the pool of top talent is spread more thinly over other degrees and then professions, eg engineering, science, accountancy, economics etc.
So there is more of a mix of people in what used to be a very typically middle class job. And with so many more universities offering these courses, the entrance grades are lower and so the calibre isn't as high overall as it used to be (doesn't apply to medicine). Of course there are still lots of very good people doing law and teaching.
I don't see why that's such a controversial view! I thought everyone thought that with the whole "degrees mean nothing these days" mantra that's often trotted out on here.
