Googling leisurely for some of the links for the piece below (which I wrote on the train with no internet access), I came across this short essay by Bertrand Russell. It is from around 1930 but seems remarkably relevant still.
His diagnosis of this continuing trend of youthful cynicism is:
The work of intellectuals is ordered and paid for by Governments or rich men, whose aims probably seem absurd, if not pernicious, to the intellectuals concerned. But a dash of cynicism enables them to adjust their consciences to the situation. There are, it is true, some activities in which wholly admirable work is desired by the powers that be; the chief of these is science, and the next is public architecture in America. But if a man’s education has been literary, as is still too often the case, he finds himself at the age of twenty-two with a considerable skill that he cannot exercise in any manner that appear important to himself. Men of science are not cynical even in the West, because they can exercise their best brains with the full approval of the community; but in this they are exceptionally fortunate among modern intellectuals.
And his suggestion as to a possible cure to this malady:
The cure will only come when intellectuals can find a career that embodies their creative impulses. I do not see any prescription except the old one advocated by Disraeli: `Educate our masters.’ […] 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! Imagine a magnate confronted with the question: `If you were to make a corner in wheat, what effect would this have upon German poetry?’
What a Stock Exchange that would be…
