Like loans to companies and individuals, startup investments, stock purchases, etc. Money that moves around is useful. Money that is tucked under a mattress is not.
The fuck you think investors do at all? What value do they create?
They definitely don't pay my wages from their own "investment". My wages are paid from the profits created by myself and coworkers working to create, market, sell, distribute the product. Soon as those profits don't hit targets investors will absolutely vote to downsize or shutter entirely, not "invest" and continue paying wages.
I'm not going to explain all of macroeconomics to you, but the whole point of this discussion is decreasing prices is bad because money stops moving. If money stops moving, you stop getting paid. Is that simple enough for you to understand or does it need to be dumbed down further?
And I'm pointing out that the rich aren't actually moving money to anyone but themselves.
So yes, the (rich) investors ARE hurting the economy for their own gain.
