I think honestly it is a question of budget -- I've been to a few funerals here, only those with the funds do not cremate these days. Otherwise cremation is a much more affordable option. The services at Chacarita are almost like a conveyor belt, you go there, there will be tonnes of families. First they will have the casket taken into one area where therre are about 4 pedestals or more, there will be multiple blessings going on at once, so your party gathers around the casket that contains the body of your relative etc. The priest will ask their name and deliver the same blessing. Then the party loads the casket back into the hearst, the car will pull out and your party will follow in their own cars and drive to the crematorium. Your party unloads the casket then carries it into the room when signalled and puts it on a literal conveyor belt and then the doors at the foot will open and it will be received by staff on the other end. I've been to 3 ceremonies like this, it is a relatively cheap way to be buried. Then it takes a few days to receive the ashes and at that point you either bury in a plot, or take home etc.
