I agree- ridiculous premise.
He never mentioned music and theater either: the opera, plays, symphonies, jazz etc. And a billionaire could hire them to perform in his home or buy out the place for a night.
And telegrams were available if you had no phone.
Clearly he never watched Downton Abbey- I know it was England, but they had wealthy Americans in the story as well. They didn’t look like they were suffering much if at all IMHO.
This reads like a high school term paper; barely researched and written because he had to write something!
I had a conversation like this the other night at the local ice cream parlor; WBill Jr. wanted to talk about what it would be like to be rich - all the "stuff" we could have, and so on.
I told him that I had a great kid, a wife that I was still head over heels for, and I'd just eaten a bowl of ice cream. How could life get much better than that?
