This is a thing that is known to most people since the end of WWII, with it's genocides – in fact what you describe is a very modernist view of the world: societies are continuously progressing into the direction of the light, with technology making things better all the time. In this world view the arrow of time has a clear direction and it is forward, while the roles of the protagonists is equally clear cut.
Many people don't really get what the postmodernists wanted: they were sick of precisely that lie. In their eyes things are not always getting better and more rational while knowledge and wisdom increases. Things get forgotten and vanish, good things get replaced by cheap things, confusion happens, intelligent people make immoral decisions while dumb people become heros etc.
It is this "dirt of reality" where things aren't as clear cut as many thinkers like them to be. This is not a problem per se, unless they try to make the reality match their ideas instead of the other way around.
