There is a maxim I apply to all these sorts of stories - the best explanation of a rule, political or otherwise, is not its purported reason for existence, it is the results. If a rule performs so badly, and everyone wants it changed, it just gets changed. If it doesn't get changed, it is usually because it is performing exactly as desired (if not always as intended). I think it is based on a mathematical theorem or something, but i have long since forgotten.
