well you could say that, but I'd say we are slave to ourselves, if you don't have needs and wants and wishes for someone else to fulfill, then how can anyone control you, I'm not really revolutionary or rebelious I just see bullshit and I want it out, in my mind the problem of connection is the biggest, since people can't really work together, we've kind of lost touch when everyone branched off to specialise, we kind of lost the common ground, now politics is a bunch of schoolkids trashing the playground.
Yes selfishness does contribute to human suffering and we are kind of responsible for what we have ourselves, still if that was a major flaw I'd be surprised, sure it's quite well spread with everyone looking out for their own self interest, I'm still not sure if that is good and evolutionary or stems from a flawed way of life that is no longer grounded.
