There is no doubt that the La Linea Ayuntamiento has substantial financial problems. Problems that if it does not resolve will result in social unrest and possibly worse. What is not a solution is to take steps that will not ameliorate but will rather worsen their problems. La Linea is a net economic beneficiary of Gibraltar's economic success and wealth.
If Gibraltar did not employ residents of La Lines, its residents would be worse off and less able to pay their municipal charges. If the people who work in Gibraltar did not rent, buy, drink, eat and make merry in La Linea, people there would be even less able to pay their municipal charges. If people cannot pay their municipal charges the financial state of that Ayuntamiento would be a lot worse than it is already.
It is not enough for Sanchez to say that his proposed toll is not aimed at Gibraltar and Gibraltarians but at the Government in Madrid, whose economic problems are known internationally. It may be that his intention is to get heard by Madrid but the affected community is not the Madrid Government, it is Gibraltar. In a hostage situation it is not an excuse for the hostage taker to say that he does not wish to harm the hostages but rather the persons that he is making demands of. Sanchez's logic is equally distorted and disingenuous.
Irrespective of what Sanchez says or the excuses he makes Gibraltar must react. A complete boycott of La linea is called for. I would go so far as to say that tobacco should not be sold for a week. It would be the fastest way to get a reaction. I wonder whether tobacco suppliers would join in that type of boycott? A short sharp economic lesson would bring some sanity to the situation that Sanchez is provoking.
