Not to in any way take away from the tragedy here, but construction workers make a fair amount of money. On top of that, there have always been fatalities associated with construction, and those numbers are far lower here than almost anywhere else. All workers are made aware of the risks during training, though I would imagine those risks aren't always in the front of wrokers' minds. It is the volume of construction that gives us so many tragedies, and that number is still very low when compared with fatality rates in developing countries with high-rise booms.
