A poverty mindset mixed with a surplus of things available to people creates hoarders. When someone without a lot of money gets something for free or very cheap, even if they don't end up using it very often, they don't want to throw it out, because if they need it later they will not be able to afford to replace it at full price. Sometimes the behavior can persist even when the person eventually gets money. They become used to living that way, and keep preparing to be poor again even after their fortune has changed.
