I understand where some of you are coming from, saying that education is almost pointless as its so expensive now, and it doesn't justify the cost. However, I'm 18 in 6th form (well technically just left!) and doing my A levels. I've applied for Uni and as long as I get the grades (which im sure I will), I'll be going to Uni.
I went to Dr Challoner's Grammar School (one of the best Grammar Schools in the UK), and from what all the teachers and advisers have said, the main statement is that you should stay in education.
With unemployment high and the state of the economy, it's best to get good qualifications now, and hope that in 4/5 years time when you come out, the economy will be in a better state and you will have a greater chance of being employed.
My dad is employing people who have been to top Universities, and they are doing nothing. He has a girl from Cambridge literally number crunching. If you don't have any qualifications it is very unlikely that you will get a decent job.
Another thing to point out, my mum told me about someone who was very depressed as he had been told that he couldn't be 'promoted' anymore as he didn't have a degree. He had been in the field of work for 10 years and was better than the new employees who were graduates with a degree, but they simply stopped him as he didn't have a degree.
This shows that you pretty much need a degree to get a good job, UNLESS you go down the entrepreneurial route which I also hope to do, whilst at Uni - another point that the contacts you'll make and resources available will help significantly in starting a business (I'm doing a Business Management + Entrepreneur module - yes you can't teach entrepreurship, but they basically help you with an idea you have, and will help you get going - turning it into a business - however, you can refuse their help and funding).
However, with uni fees increasing from 3.3K to 9K next year, you want to get into education now, otherwise you'll be left with an extra 20K or so debt.
I also want to start up and run my own business, however I feel that will be much harder without a degree also. Especially trying to get a loan; with a degree you will be much more credible, and as I mentioned, the resources and help available will make it much easier.
