I would suppose the regarding Latinate and French words as more "refined" or "educated" is a hold-over from the effects of the Norman Conquest. The English upper-classes have always had a sense of inferiority in comparison to the French, and at one time, if not still to this day, strived to imitate them wherever possible. Many countries have a similar relation with what many consider to be a grander power, Ireland of course is one of them.It seems to be just a question of commonsense. Probably the English-speaking people would use language far more accurately if plain English were favored. See for example Orwell :
In his 1946 essay "Politics and the English Language", George Orwell wrote:
Bad writers –especially scientific, political, and sociological writers– are nearly always haunted by the notion that Latin or Greek words are grander than Saxon ones.

In 1946, writer George Orwell wrote an impassioned essay, "Politics and the English Language", criticizing what he saw as the dangers of "ugly and inaccurate" contemporary written English - particularly in politics where pacification can be used to mean "...defenceless villages are bombarded from the air, the inhabitants driven out into the countryside, the cattle machine-gunned, the huts set on fire with incendiary bullets...".
