How can we be so sure? Do you have data for these accusations - because so far you simply claim what you are saying. 90% is quite a lot of "evil".
Imagine even if there are people who want to do their job well, how the hell should they get all the information they actually need? Then again everybody has agendas and his own idea of "right" or "wrong" - how should the "right one" gain the necessary support?
Imagine you realize you can not do it anymore, are you going to out yourself to the entire company to find like mindet people? Is anyone going to want to join you? ^^ I really doubt that...
I probably would keep my mouth shut and try to quit the shitty job, since I value moral over material wealth, but do not serve anybody being dead in a ditch.
Who knows, let us be happy that we are not in such a dilemma, it is bad enough to be on the recieving end
