If you’re talking earningwise : yes ok money initially doesn’t belong to them but the person who earned it…but they may be dead so it’s not like you’re going to bury the money with them and not use it for any thing such as a college fund for their child. Keeping it for the dead person who earned it would just be illogical. Pay off their debt, pay taxes, then use it for their family.

If you’re talking estate wise: it belongs to the generation that was passed down to on the will. But again, still pay their debt and taxes first.

If you’re talking spiritually: it doesn’t belong to any of us and it is but a construct we use for keeping these flesh bags we wander around in alive. It really doesn’t fulfill any further use than a catalyst of change but yet some people hoard this thing like it’s going with them to the next life which I’ve already covered is illogical thinking and every billionaire should be considered in a state mental illness and examined as such.
