If you live in Europe, and specially US, you are already part of the shareholders and will profit from it (on average). More or less than other actors in the country, but definitely more than those ones not being under these central banks policies.
I swear people have no clue how banking works.
No amount of annual profit returned to the Treasury has ever outweighed the negative effect of Fed induced business cycles and bailouts.
Money is there to be used for transactions. Using money to save is literally the opposite how you are supposed to use it.
If anything, people witholding the medium of exchange against interest are what is causing business cycles and bailouts.
