I don't see the problem. They have money that they don't want to spend for whatever reason. It's their money and nobody else's business. But hey, it's the internet, so everything is fair game.
The question could be turned around: what incentive is the OP giving them to spend, and in what way would they benefit?
“The reasonable man adapts himself to the world: the unreasonable one persists to adapt the world to himself.
Therefore all progress depends on the unreasonable man.” ― George Bernard Shaw, Man and Superman
I think the counter argument is that thing Bush called "compassionate conservatism", or what some call "responsible capitalism".
That is, considering the vast disparity in wealth distribution in this country, would those holding the money be acting in a responsible and humane way if they raised wages a bit? Increased benefits a bit?
They are the investors.
Hoarding cash during the recession? Fine. Hoarding cash when the recession is over? The companies better give the investors a good reason is all I can say.
If I were the investors I'd start questioning soon.
