When you draw a set diagram and set A is inside set B, you are saying that "All A are B."

The diagram, however, does not necessarily imply that there are some members of B who are not members of A. If you want to make that point, you should annotate or label your diagram to make that clear.

Is it that they haven't lasted, or are those fortunes just operating under other names?

I found this interesting note on the Internet. "America is exceptional for the number and size of its fortunes, and for the fact that they don’t seem to last. No country in the history of the world has created so much wealth as has the United States. Nor has any country created so many fortunes of legendary size. The names are still household words: Vanderbilt, Astor, Carnegie, Rockefeller, Morgan, Gould, Mellon, Harriman, Frick, Huntington, Croker, Flagler, Duke, and Hearst. And yet none of those names are among the great American fortunes of today. Indeed, only three of those names, Rockefeller, Hearst, and Mellon, make the Forbes list of today’s 400 largest fortunes, and not one is near the top. What happened to these vast fortunes? Why don’t American fortunes last as so many European fortunes have? "

I stumbled upon this site from Facebook. I was reading some comments and noticed that there seem to be a lot of comments by Ron Larson. It took a while, but I noticed in the upper left corner that this book was written by Ron Larson. It's kind of interesting knowing that I can respond to a comment left by the author of the book.

Note that the cartoon character in the Checkpoint is not Monopoly's Rich Uncle Pennybags. One of our artists drew a different one. If you want to see Hasbro's cartoon character, search for "Rich Uncle Pennybags" in Google's Images.
