Tradition, marketing, after all its a big money maker for the industry.
I honestly believe there is a shift toward cremation now. At least as far as our family members and siblings.
Something that seemed strange to us decades ago with every family member, parents, aunts, uncles, grandparents, having traditional funeral homes, showings, burials ect. I guess the question could be asked, why?
I dont know anyone of my family members/siblings that want any of the above anymore, we all want to be cremated. I mean, you're gone, go in peace and we do not want to burden others with arrangements, costs, stress, it's stressful enough. I think also many family members are in many more places around the country than decades ago adding to more stress and arranging things.
This change in thinking towards cremation is big for us because no one in my family circle ever knew anything different. Growing up one half of my family tree was hardcore Italian and everything that was done was the whole shebang, weddings, funerals and everything in-between. That even goes for the other half as well.
