Relevant Bertrand Russell

" A man is not allowed to practise medicine unless he knows something of the human body, but a financier is allowed to operate freely without any knowledge at all of the multifarious effects of his activities, with the sole exception of the effect upon his bank account. How pleasant a world would be in which no man was allowed to operate on the Stock Exchange unless he could pass an examination in economics and Greek poetry, and in which politicians were obliged to have a competent knowledge of history and modern novels!" -Bertrand Russell
