Both myself and DH went, but looking at his career path he didn't really need to, and is in fact much happier now he has a hands-on ladder-climbing type job that uses skills his degree completely passed over than he was as a tie-wearing graduate manager. Having said that, he had a great time at universiyt and had a lot of opportunities and experiences that he wouldn't have had otherwise.
On the other hand, I love my job, and there's no way I could have got into it without two degrees and the practical and theoretical experience they gave me.
I think it's unfair to push people into university who aren't really sure what they want to do - there's a huge range of post-16 and post-18 options out there that would suit some people a whole lot better than university would, and there are lots of careers that are more suited to an apprenticeship-type training period than a classroom-based formal qualification.
I just wish young people were better informed about all this - my academically-orientated school basically reduced career choice to Lawyer, Doctor or Journalist, with the outre option of Obscure Academic for the classics girls. Rubbish really, and I'm quite pleased I'm none of the above.
