change, either an improvement on the current or a complete overhaul, is good so long as it adheres to the original aim/intention/purpose.
Yes, that is a good theme... people need to focus on their intended outcome while change is taking place.
There exists in us a primordial fear of the unknown, which is brought about by change. ---I like this sentence!!!
However, change is always good so long as it affects society as a whole, positively and allows for progress and development.----- Well... this might be an oversimplification. And it might not have any meaning, because it says, "Change is good as long as it is positive." That is like saying, "Change is good as long as it is good."
