Becoming rich in times of crisis

A young man asked an elderly rich man how he made his money. 'Well, son, it was 1932. The depth of the Great Depression. I was down to my last penny, so I invested that penny in an apple. I spent the entire day polishing the apple and, at the end of the day, I sold that apple for ten pennies. 'The next morning I bought two apples, spent the day polishing them and sold them for 20 pennies. I continued this for a month, by which time I'd accumulated a fortune of £1.37. 'Then my wife's father died and left us £2 million.'
