Isn't that what most governments do (and probably will continue to do)? Democracy and equality are just useful foils. They help hide the tough decisions that may or may not be mistaken, but have to be made.
Aizen certainly isn't fighting for 'change'; and I don't think the Vizard care for it either. However we did see Soul Society 'opening up' somewhat after the original ryoka incident with Ichigo trying to save Rukia. Change on a grander scale may only be achieved slowly as I see it; but as you say a war with everyone giving their all will most likely be conducive!
