Profit over people if we're being honest. They structurally ignored this building for years, but it makes them money. It's a classic example of the soulless elites living life in their mansions and their boats while us regular folk are put in danger.
That truth does not apply here, for this was a condominium, that is, each unit, apartment, was owned by those that lived in it. They are all just regular people, mostly retirees. The building was not properly maintained because they put it off to save money. That is very common, because no building ever fell like that. (P.S. - I still believe it was a demolition job.)
