That’s actually true worldwide. Wanna see how an economy looks like after over 30 years of almost uninterrupted conservative leadership? Look at where Germany stands now. Crumbling infrastructure, worst Internet in Europe, industry unable and/or unwilling to open itself to modern technology (best example being the German car industry).
Also fits Galadriel and her decision to rather remain Galadriel and go into the west instead of become the “Dark Queen”. She’s literally the oldest living being besides Sauron itself residing on Middle Earth by that point.
EDIT: ok, one of the. Still hella old.
