Lol compared to what some of my friends have to travel for work (those in the trade etc) each day, travelling 7 miles for work is pretty chill. I dont usually agree with old people, but in this stance us young people have it too easy. If its saturated in London, why not relocate? Plenty of jobs in East Anglia, the North etc. During my pre reg applications I got rejected by most multiples in London, apart from one which offered me a place in Bristol. If you need to relocate, then so be it, in the current economical situation plenty of people have had to do it and you wont find much sympathy regarding this imo.
