There are also 18 year olds who choose an apprenticeship or job precisely because they'll have more money to pay for fun and parties.
I'm one who didn't go to Uni, despite my Dad (who worked at UCL) telling me what a great life students had (back in the 60s).
I wanted to leave home and enjoy myself, which I did. One of the benefits was the large number of concerts I went to, ranging from the Tamla Motown Roadshow to Segovia and many others in between.
I had no idea of what I wanted to do until, in my mid twenties I met an accountant who was looking into the path lab where I worked and I asked if he would explain some of the finer points of book-keeping, having taught myself basic book keeping. He suggested that I should think about going into articles, because women made good accountants. So I did, just before the rules change to making the profession graduate only. At the time women in the accountancy and law professions amounted to about 3% but now it's around half, if not higher.
