A fabulous new chapter! It's always a bit tragic to see innovation run right up against exploitative labor practices, though this was very much the norm in the 19th century. I'm surprised by how violent that turned so quickly! Then again, the practices are described as exploitative for the era.
These were common in Chilean history. In only one such event, the Santa Maria School Massacre, in one day the Army killed more people (by some estimates) than the total deaths attributed to Pinochet.
