I think you are wrong about the lack of interest in personalization. You can see it at the conventions. Major casket manufacturers are slowly testing the waters with a template style personalization, i.e. cap panels, corner pieces. The problem is that the consumer is not aware that there are other options than what is being offered to them by the funeral homes.
It doesn't occur to them that they can ask for and possibly receive something tailored specifically to their loved one. And the average (not all!) FD does not want to bother with options outside his or her comfort zone. Or heaven forbid, outside their corporate umbrella.
Personalization is coming but it will be limited if left to Batesville, Mathews, York, etc. You may surprised in a few years how close EI came, too bad there wasn't someone else at the helm.
