Ever since the fallout of the Great Recession we've had to deal with the reality of dead money in the system being much larger than what's in circulation. Heck, I suspect that's been the case for decades earlier than that but over all I think now we can account for it better due to our use of computers to keep track of the balance sheets. So in effect we got a better picture of what's going on but not the reason for it happening. And it would be nice if economists would take chances on less mainstream theories in economics to see what actually works rather than keep using overly simplified models that pretend to be right when they can't even match on the most basic trends in the economy.
