I'm sure they don't, but finance people are actually pretty unique creatures in my limited experience. Talk to someone working in criminal justice, for example, and they'll happily own up to all the ways their work creates human misery and they'll probably float some interesting ideas about how the system is broken.

Then go out and try to find a banker, trader or mortgage person and try to get them to accept some actual blame for the highly-leveraged, taxpayer subsidized horror their profession periodically unleashes on the world. It's surprisingly difficult to do, given the obviousness of the problems.
