Investment banking is very special industry. People are lured to it by above average salaries and opportunities for quick career progression. For majority of students Investment Banking is the most desired career - it is prestigious and it seems to be lucrative.
However, for many of these people career in other industries (like in FMCG, Marketing etc.) would be a much better option. First, because of much lower competition you will be able to progress much faster. Surely the salary of a managing director in Lehman Brothers may be twice as large as the salary of managing director working for example in Mediacom. However, for a clever guy the chances of becoming a managing director in Mediacom are at least ten times higher than chances of becoming a managing director in Lehman Brothers, and so the expected income from working in Mediacom (which is here given just as an example) would be higher than expected income in Lehman Brothers... (Intuition: It is easier to make a career and become MD if you are the best among averages then to do it when you are average among the bests) . Second, you will be able to live normal life, not the life of IBank nerd who is sitting in work for 15 hours daily.
My subjective list of industries that may provide lucrative opportunities are:
- IT - (Microsoft, Oracle, IBM, etc)
- Energy - (Shell, BP, Exxon, etc)
- FMG - (P&G, Mars, Unilever, L'Oreal, etc)
- Marketing/Reseach/Media (Mediacom, IPSOS, BBC, etc)
and many, many others.
Although it seems that IBanking is the only interesting career, this must not be true. It's possible there are other careers that you find more interesting, and that would provide you with higher income on average. Your life - your choice.
