This applies more to Beta Js but still.
You sound kind of overly harsh/bitter when you talk about the Beta scheming thing but I think you are spot on. I am a Beta P but I find myself scheming like that often. LoL I mostly do it though if I feel trapped inside a Delta organization and the only way out is for me to manipulate others. As if I used honesty or anything non-scheming/obsequious, I'd just make things worse for myself. So we Betas can be like that for good reasons.
