The “goldfish”: being the confessions of a successful man by Arthur Cheney Train( 1914)
The book is a story about a rich man’s life morals and ethics. I do not know if it is fiction or not, since the write is nonfiction author.
From the book’s introduction:
We have grown literally afraid to be poor. We despise anyone who elects to be poor in order to simplify and save his inner life. We have lost the power of even imagining what the ancient idealization of poverty could have meant the liberation from material attachments; the unbribed soul; the manlier indifference; the paying our way by what we are or do, and not by what we have; the right to fling away our life at any moment irresponsibly the more athletic trim, in short, the moral fighting shape. … It is certain that the prevalent fear of poverty among the educated class is the worst moral disease from which our civilization suffers.”
