I identify with your insight. My former self before awakening involved work in marketing communications; i.e., manipulation of the ego to get people to spend money on something they might not otherwise purchase. Outright lying was encouraged, and resistance always acquiesced into a compromise of subtle manipulation of "truth." It only fed the world, and my own ego, in negative ways. My new careers I've had during/after awakening involve using the same skills I have with people and discerning emotions, but not to manipulate -- only to assist them to find their own way; to hold space for them without ego. I'm not always perfect. Concepts of right livelihood and right effort help me when I fall down, as does honest discourse with those whom were hurt when I do.
Right livelihood seems to be about feeding the self so that it can continue to practice, and in turn, perhaps help others to do so.
I also like the concept (a Zen practice?) of leaving a little something after a meal on the table when I leave to clear my plate as an offering for the Hungry Ghost. It fosters compassion further while receiving bounty that a livelihood affords. And reminds me that there are people out there who do not, for various reasons, fit into this world in a way that enables them to practice right livelihood. That they are a part of who we are as well, and need nourishment too, if we can find a way.
