Apple, not the markets, is buying the shares. In a Ponzi scheme you can't get out more than you put in. So how the hell is this possible? Oh because Apple dips into its bank account and pays you what the markets can't reconcile. A freaking Ponzi scheme.
The question is always there. When shares go up, who is responsible for paying you that increase.
Some of you are scholars in this corrupt, economic zeitgeis.
