How is this a problem? You don't save to hoard, you save to use that money later. Delaying the urge to consume in favor of investment is very much correlated to the growth of an economy (afaik, not an economist but a somewhat interested layperson).
In a modern economy "savings" equals investment. Even using a bank deposit account transforms one persons savings into another's business loan or mortgage.
This seems to be a widely held misconception - that savings are economically inert - a bit like a squirrel's nut hoard.
Businesses don't need loans when they don't have customers with money to spend.
This, is a widely held misconception. A bank is no longer allowed to re-invest more than a small proportion of it's customers' savings.
