poweraMany African families spend fortunes burying their dead
Basically my whole family have signed our bodies over to the local medical school. They make all the arrangements and pay for everything as soon as they're notified upon death. They'll normally give you the ashes upon cremation after a year or so, but personally I've given them permission to completely skeletonize me and keep the skeleton indefinitely.
This helps society by helping student doctors learn, and it removes all funeral hassles and expenses. We can still do more low-key memorial ceremonies without needing a body. I realize this path doesn't work for everybody, especially those with certain religious beliefs, but we all just love the idea.
And for folks that do want to bury the body, it can be done way cheaper than the funeral industrial complex would have you believe. Our church keeps a simple coffin on hand that the family can use at cost. And we have folks who will prepare the body and bring it to the church. The only part we don't usually do is dig the grave. Cemeteries usually include that in the cost of the plot.
