Which is why the term "cash," to those in finance or familiar with its lingo, is understood to actually mean "short term treasuries" and other things you would find backing a money market account, unless the context very specifically calls for distinguishing those two things.
That's exactly what I'm saying, “investment” has a precise meaning in economics, it's the increase of productive capital (example: building a data center is an investment).
There are no Scrooge McDuck cash vaults.
