They may not move their country forward, that doesn't mean they don't move the world forward. Say what you will about the French revolution's effect on France but it greatly influenced the spread of democracies and republics world wise. Similarly the presence of socialism(in the production owned by the people sense) hugely encouraged improvements in working conditions in countries that feared similar upheaval and loss of property.

But I wouldn't argue with you that the majority of these 'elite trimmings' set the society back. The question is after the set back does it move forward faster than it was or in a better direction (Often the answer to this would be hugely reliant on your personal values).
