"Ultimately, systemic changes of this magnitude requires a movement that includes all of us."
But you will have to assume that the movement will not include "all of us", because all of us will not be interested in joining since there are many who are pretty happy with the way things are. You will have to build a movement of people who will resist the temptations of society as it is now, because not everyone is going to get with the program and want less, and you can't make them. You should be trying to figure out how to simply get the people you know personally to make the changes you think are needed, like your family and friends. If you can't get them involved, what hope do you have with millions of strangers?
Or you can be just and caring, and let everyone else do what they want.
