The Mosley Memorandum won the support of the economist John Maynard Keynes, who stated that "it was a very able document and illuminating".[71] Keynes also wrote,

"I like the spirit which informs the document. A scheme of national economic planning to achieve a right, or at least a better, balance of our industries between the old and the new, between agriculture and manufacture, between home development and foreign investment; and wide executive powers to carry out the details of such a scheme. That is what it amounts to. ... [The] manifesto offers us a starting point for thought and action. ... It will shock—it must do so—the many good citizens of this country... who have laissez-faire in their craniums, their consciences, and their bones ... But how anyone professing and calling himself a socialist can keep away from the manifesto is a more obscure matter."[72]

According to Lady Mosley's autobiography, thirty years later, in 1961, Richard Crossman wrote: "this brilliant memorandum was a whole generation ahead of Labour thinking."

Mosley was critical of Sir Winston Churchill's policy as Chancellor of the Exchequer. After Churchill returned Britain to the gold standard, Mosley claimed that, "faced with the alternative of saying goodbye to the gold standard, and therefore to his own employment, and goodbye to other people's employment, Mr. Churchill characteristically selected the latter course."

This is the clearest explanation why CHurchill adopted such a policy.

Mosley was an early supporter of Keynes.

Mosley's economic programme, which he coined "socialistic imperialism," advocated for improved industrial wages and hours, the nationalisation of electricity and transportation, slum-clearance, the protection of "essential industries" from "unfair competition," and higher government investment in education, child-welfare, and health services.
