Interesting indeed.
The Lancashire blacksmith's son and leader of the Communist Party of Great Britain stood in front of the group of high-flying young Left-wingers at Cambridge University.
Harry Pollitt told them: 'Don't join us. Work hard, get good degrees, join the Establishment and serve our cause from within.'
It was a few years after World War II and they took Pollitt at his word. Within a decade, the Communist Party foundered (its membership peaked at 60,000 in 1945) as Pollitt's bright young devotees infiltrated the Establishment. They were soon exercising considerable influence in universities, the state education system, publishing houses, the legal hierarchy and the civil service.
Seems their plans worked perfectly.
