This is an old thread, but I just stumbled across it.
I think it's important to distinguish between bankers and big banks (Bank of America, Wells Fargo, Chase, etc.). Almost everyone employed at any bank is referred to as a "banker". It's ridiculous to think that they're all "evil scum".
However, when big banks are the issue, a mere modicum of research will show just how evil their tactics are.
So, yes, big banks are "evil scum", but it doesn't follow that all bankers are evil scum.
