I am an old bird. When I was young, you could make a perfectly good career for yourself in most fields with professional qualifications alone. Only high flyers needed a degree. In those days, only 2% of the population had degrees and the degree courses were universally of a very high standard.
Nowadays, every b*gg*r has a degree. There are people walking around with degrees now that wouldn't even have got into grammar school in my day. Many of them are semi literate. Certainly degree course standards have been dumbed down.
When you apply for a job now, you are invariably interviewed by someone with a degree. These people often seem to believe that no one without a degree can possibly be much use.
My advice? In this day and age, don't under any circumstances get caught without one. It doesn't matter whether you get one now or in a few years time when you've got some experience. But make sure you get one. Try and get a degree in a useful subject if you can, but if you can't get one in the Humanities. Any degree is better than no degree.
