The Saying We Know but Never Think Through People have no trouble accepting that the head of the family has the final say at home, the owner calls the shots at a company, and the general commands in the army. Just as readily, they nod along to the old saying that money makes the world go round. It’s just odd that at the exact moment when the logical conclusion of that sentence should follow — namely, that whoever owns that money runs the world — their signal suddenly cuts out.  Coincidence or ignorance or if it’s out of sight, it’s out of existence?  And now you know why it is Elon Musk, of all people, standing at the top of the billionaire rankings.
