Stupid! If everyone on Earth had a billion dollars, a loaf of bread would cost $4 billion.
And if there were that much gold, it would be cheaper than marshmallows.
Yes, there is an awful lot of stupidity in the world, and much of it is writing articles.
That concept is so simple to understand that even Gilligan’s Island did an episode on what happens with an over abundance of gold. That makes the author less educated educated in economics than the writers of a 60’s sitcom and the kids that watched it.
