as long as you can find £110,000 and are reasonably intelligent
I would disagree, it is far from easy and people from very high ends of the job spectrum (lawyers etc) haven't managed to get onto a ctc programme. I don't know what your current situation is but I would encourage you to try the CTC selection test for an airline programme and see if you still hold the same views after it. It isn't just aptitude/maths etc, the interview I would say is even harder.
