It's not hard to see where it comes from, but intelligent people should be able to see the financial sector with a bit more nuance than knee-jerk hatred. There are many good reasons not to enjoy working there, but hand-wavy self-certain assertions that everything that goes on there lands somewhere between net negative and plain evil is just disingenuous.

Go there, learn about it, make some money while you're at it. Leave if you don't like it - it's not a sect.
