First of all, I think you'll find that retail deposits provide the base for a lot of banks' leverage. If they didn't need the deposits they wouldn't be so vehemently against separating retail with investing arms. In short, it's free money for them, and it's a lot too, so don't dismiss it entirely.
Secondly, you have completely misunderstood my post. I said in my post I am clearly referring to bankers - all my posts have been about bankers and bankers only. Admin staff and receptionists or PAs are not bankers now are they? I find your direct comment that I feel big somehow that a poor PA lost her job and will get her house foreclosed actually insulting to my intelligence as I would have never implied or thought of anything like that. On top of that there was no 'snigger' in what I said, only in the way you read it. I was simply making a comment about the over-use of the word 'talent' when talking about bankers, trying to point out that the talented ones were not fired (in response to someone asking how could it be that all these talented ones brought banks down to their knees - well, the talented ones didn't, the rubbish ones did and that's why they largely got fired).
Your post has actually reinforced my last point, that the talented bankers were kept on the job, not let go, simply because they make lots of money for the bank.
Finally, adding to 'who got canned', while a lot of admin staff were canned (but we are talking about bankers aren't we?), scores of analysts/associates were canned as well so yes, a lot of real bankers were indeed canned.
