The above are prepaid cards of the kind used by urban buses in Rosario, worth 6 trips each. The one on the left shows the price of the bus ticket until yesterday (AR$1.20, discounted to 1.15 in 6-trip cards); the one on the right has the current price today, December 26 (AR$1.40, discounted to AR$1.35).
The reasons for the increase are (again) easily summarized: 1) inflation, affecting fuel, other supplies and general maintenance of the buses, as well as administrative expenses, etc.; 2) the mob that passes for a bus driver union got them a salary that rivals that of a well-established doctor, lawyer or architect; 3) the national government sends most fuel oil subsidies (keeping fuel oil cheap for public transportation) to Buenos Aires and its metropolitan area. Reason #1 finds the government simply in denial; reason #2 is fait accompli time and time again; reason #3 is a result of a federal republic that is such only on paper.
Just after Maurice the Menace was elected Chief of Government of BA, Néstor Kirchner ordered AR$600 million in subsidies to public transportation taken away from the capital district, but not in order to redistribute them among the provinces. Buenos Aires City, holding the highest standard of living in Argentina, and amid a shortage of fuel and energy everywhere, somehow continues to enjoy ridiculous cheap bus, train and subway fees.
