By "someone else's" you surely mean "the bank's money". I don't think individuals are going to benefit from this, just a few large players around the world.
In fact, there's most of the money the banks loan is not "somebody else's" at all, it's "loan money".

There is (in simple terms) as much money as people can reasonably borrow.
