No, you're ascribing will to a blind and undirected process. Squirrels that survive in recent years and decades bury more food than they ever eat, whether that specifically helped them against certain selection pressures or whether it vestigially remains as a non-impacting behavior.

In my view the effects on the ecosystem are way more important than whatever pressure creates a behavior. For both squirrels and trillionaires.

what political and social pressures are squirrels under that trigger them to gather food for other animals?
