Problem: Pink Floyd - The Wall is a 1982 British live-action/animated musical drama film directed by Alan Parker with animated segments by political cartoonist Gerald Scarfe, and is based on the 1979 Pink Floyd album of the same name. The film centers around a confined rocker named Pink, who, after being driven into insanity by the death of his father and many depressive moments during his lifetime, constructs a metaphorical (and sometimes physical) wall to be protected from the world and emotional situations around him. When this coping mechanism backfires he puts himself on trial and sets himself free. The screenplay was written by Pink Floyd vocalist and bassist Roger Waters.

Even before the original Pink Floyd album was recorded, a film was intended to be made from it. However, the concept of the film was intended to be live footage from the album's tour, with Scarfe's animation and extra scenes. The film was going to star Waters himself. EMI did not intend to make the film, as they did not understand the concept.  Director Alan Parker, a Pink Floyd fan, asked EMI whether The Wall could be adapted to film. EMI suggested that Parker talk to Waters, who had asked Parker to direct the film. Parker instead suggested that he produce it and give the directing task to Gerald Scarfe and Michael Seresin, a cinematographer. Waters began work on the film's screenplay after studying scriptwriting books. He and Scarfe produced a special-edition book containing the screenplay and art to pitch the project to investors. While the book depicted Waters in the role of Pink, after screen tests, he was removed from the starring role and replaced with punk musician and frontman of the Boomtown Rats, Bob Geldof. In Behind the Wall, both Waters and Geldof later admitted to a story during casting where Geldof and his manager took a taxi to an airport, and Geldof's manager pitched the role to the singer, who continued to reject the offer and express his contempt for the project throughout the fare, unaware that the taxi driver was Waters' brother, who promptly proceeded to tell Waters about Geldof's opinion.  Since Waters was no longer in the starring role, it no longer made sense for the feature to include Pink Floyd footage, so the live film aspect was dropped. The footage culled from the five Wall concerts at Earl's Court from 13-17 June 1981 that were held specifically for filming was deemed unusable also for technical reasons as the fast Panavision lenses needed for the low light levels turned out to have insufficient resolution for the movie screen. Complex parts such as "Hey You" still had not been properly shot by the end of the live shows. Parker also managed to convince Waters and Scarfe that the concert footage was too theatrical and that it would jar with the animation and stage live action. After the concert footage was dropped, Seresin left the project and Parker became the only director connected to The Wall.

Problem: Warren Edward Buffett (; born August 30, 1930) is an American business magnate, investor, and philanthropist who serves as the chairman and CEO of Berkshire Hathaway. He is considered one of the most successful investors in the world and has a net worth of US$87.5 billion as of February 17, 2018, making him the third wealthiest person in the United States and in the world. Buffett was born in Omaha, Nebraska.

Warren Buffett's writings include his annual reports and various articles. Buffett is recognized by communicators as a great story-teller, as evidenced by his annual letters to shareholders. He warned about the pernicious effects of inflation:  The arithmetic makes it plain that inflation is a far more devastating tax than anything that has been enacted by our legislatures. The inflation tax has a fantastic ability to simply consume capital. It makes no difference to a widow with her savings in a 5 percent passbook account whether she pays 100 percent income tax on her interest income during a period of zero inflation, or pays no income taxes during years of 5 percent inflation.  In his article "The Superinvestors of Graham-and-Doddsville", Buffett rebutted the academic efficient-market hypothesis, that beating the S&P 500 was "pure chance", by highlighting the results achieved by a number of students of the Graham and Dodd value investing school of thought. In addition to himself, Buffett named Walter J. Schloss, Tom Knapp, Ed Anderson (Tweedy, Browne LLC), William J. Ruane (Sequoia Fund, Inc.), Charles Munger (Buffett's own business partner at Berkshire), Rick Guerin (Pacific Partners, Ltd.), and Stan Perlmeter (Perlmeter Investments). In his November 1999 Fortune article, he warned of investors' unrealistic expectations:  Let me summarize what I've been saying about the stock market: I think it's very hard to come up with a persuasive case that equities will over the next 17 years perform anything like--anything like--they've performed in the past 17. If I had to pick the most probable return, from appreciation and dividends combined, that investors in aggregate--repeat, aggregate--would earn in a world of constant interest rates, 2% inflation, and those ever hurtful frictional costs, it would be 6%!
