The 'false' banker? Oh, that's me!
There is this species that you do not notice much. It is a human species, a species which is visible only at two very specific times: when some insomnia ridden communist journo uncovers a very large hotel bill to criticize the excesses of capitalism or when irate populist politicians need to blame someone for corporate failures originally instigated by their own populist measures.
If you meet a specimen of this species, you would probably find him keen to network with you if you have a large business or if you are a decision maker in a large organization. On asking, he will very discretely call himself a 'investment banker' with a company that has some vaguely Jewish (or in India, Marwari) sounding name.
You might think he works with an organization comparable with your standard Central Bank or State Bank of Bikaner and Jaipur, but that is where you are wrong. Or, to put it correctly, that is where you would begin to be wrong. For, on digging deeper, you shall find that he is nowhere interested in your standard savings and current accounts or is not even remotely linked to them. His primary competency lies in ensuring that the chaotic world of big finance remains chaotic :). He will, in all probability, use big words like "zero coupon convertible bonds" or "highly leveraged management buyout" or will talk about mythical sounding creatures like the "white knight".
Anyways, you get the idea. The purpose of such an explanation - I've become one of them, I've defected and have joined Lazard (India) in Mumbai. Don't blame me, what could I do, I was ensnared by the intrigue of finance, the glamour of deals.... I'll cut it, you know the rest.
