Well, Catalunya has more than earned and paid for its way out. It is not that there are no arguments on the other side but why should Catalans be alienated like that? They are known to be a generous nation and I don't think they would just turn their back on their neighbors should they be in trouble but it has turned into a permanent mandatory funding of questionable spending and handling of public finances in various part of Spain and that is also true for Galiza and Euskal Herria to a lesser extent. This is my understanding of the situation.
