For you non spanish speakers, i would like you to notice the price of public transportation in Chile, wich was 750 pesos at the time (1 dollar of 2019 money), and is still the best bang for your buck system of public transportation in the world (the buses have heaters and air conditioners, and the metro access, wich is arround the speed of california’s bart, is included in the ticket).
It is still very much subsidized by the government in construction and maintenance tho.
