Don't forget that this guy full name is: William Henry Gates III.

He is not your friend Bill from across the street that most of people could compare with.

Next you'll be telling me ascots aren't standard morning wear. (One of my favorite cartoon alter egos as a child was Henry Cabot Henhouse, III.)

Still this is the whole point of the article, he makes a reasonable example.

Aren’t most people called Bill actually named William? I actually know a William III and he’s a not-rich ROTC kid. Bill Gates did have money but i’m not sure the degree to which his name is an indication of that
