I can't speak for the parent, but some people value experiences over things
Additionally, many people who like to buy 'things' are getting them for the experiences they provide. For example, it's hard to argue that someone who buys a VR system or a hot tub isn't getting 'experiences' when they use them with family and friends.
Just something to consider if you ever use this to berate people too 'materialistic' for your tastes.
