He speaks to his sons about joining his business. All three decline. They want to go to the fancy, expensive college that will wipe out a substantial chunk of the two million dollars their father has worked for. He offers to give them paying jobs, right away, and promises they will eventually take over the business and help grow it to make more money. The four of them, he tells them, can grow the business to the point where they can all easily make an excellent living. The three sons persist.
So he gives in, and his three sons attend college. The first majors in poetry, the second in art history, and the third in dance. They go on to make a spotty living, as compared to the steady income of their father.
The father, as he grows older, wishes to pass some of his responsibility to a subordinate. By this point, his business employs fifty plumbers. With no son to inherit his business, he chooses his most loyal employee.
He dies some years later, leaving his sons each five hundred thousand dollars. All three spend it on an increased standard of living; it lasts each around seven years. After which they are again broke.
The plumber's subordinate, meanwhile, has grown the business to over one hundred employees. He was worth over fifteen million dollars, and was exploring the sale of the company to another, a deal that would likely net him roughly twenty million dollars personally. He lived happily ever after.
