Degrees are pratically a joke in this day and age. Only if you intend on becoming a Lawyer or a Doctor or any other specialist job are they worthwhile. For eveything else they are a "get your foot in the door" mechanism and a very expensive and time consuming one at that.
Even as a computer programmer i learnt vastly more at both A-level and the first couple of months of my job than i did at Uni. If i had not gone i would probably be earning vastly more than i do now too.
A lot of people just see it as an easy 3 year pissup.
