Even if you had a point (I'm not claiming anything one way or the other) that point is poorly served by a flippant passing comment. Why would being a wealthy country make someone more adept at misleading their populace? If they were, what would be the benefit?
As a PhD student doing research in data analysis, I support governments being open with data whole heartedly. UK government schemes like this [1] are invaluable.
