I have a notion (cemented this year as I've thought about it more) that beyond a certain level, most referees are much of a muchness (and a minority are not good enough with too few of them facing reclassification). To that end, I don't think there's a referee out there who really comes close to what the game demands. Not a single one. It's probably not possible for anyone to be 'good enough'
Either there's pervasive problem with refereeing culture, the rules, the way they're inconsistently interpreted and taught, or the culture of the game and the default behaviour of castigating the officials, but there's a cavernous gap between expectation of how good refs should be and how good they actually are.
Personally, I think all of the above are true and I think blame is shared throughout the game
Nothing will change because the I have no faith in the governance of rules (Laws FFS) and refereeing, but more of an issue is that the culture will never change because it's all driven by the financial success of the game and the American style circus is selling extremely well, so despite noises to the contrary, no change for the better is ever forthcoming. Behaviour in the elite game is getting evermore ridiculous, but it sells so who cares if it's at the expense of a floundering community of referees
