ing saved exceeds the amount being invested – which can happen if interest rates are too high – then unemployment will rise. This is in part a result of people not wanting to spend too high a proportion of what employers pay out, making it difficult, in aggregate, for employers to make a profit. Another key theme of the book is the unreliability of financial indices for representing an accurate – or indeed meaningful – indication of general shifts in purchasing power of currencies over time. In particular he criticised the justification of Britain's return to the gold standard in 1925 at pre-war valuation by reference to the wholesale price index. He argued that the index understated the effects of changes in the costs of services and of labour. In 1927 he wrote, "We will not have any more crashes in our time."
Keynes was deeply critical of the British government's austerity measures during the Great Depression. He believed that budget deficits were a good thing, a product of recessions. He wrote, "For Government borrowing of one kind or another is nature's remedy, so to speak, for preventing business losses from being, in so severe a slump as to present one, so great as to bring production altogether to a standstill."
At the height of the Great Depression, in 1933, Keynes published The Means to Prosperity, which contained specific policy recommendations for tackling unemployment in a global recession, chiefly counter-cyclical public spending. The Means to Prosperity contains one of the first mentions of the multiplier effect. While it was addressed chiefly to the British Government, it also contained advice for other nations affected by the global recession. A copy was sent to the newly elected President Franklin D. Roosevelt and other world leaders. The work was taken seriously by both the American and British governments, and according to Robert Skidelsky, helped pave the way for the later acceptance of Keynesian ideas, though it had little immediate practical influence. In the 1933 London Economic Conference opinions remained too diverse for a unified course of action to be agreed upon.

Keynesian-like policies were adopted by Sweden and Germany, but Sweden was seen as too small to command much attention, and Keynes was deliberately silent about the successful efforts of Germany as he was dismayed by their imperialist ambitions and their treatment of Jews. Apart from Great Britain, Keynes's attention was primarily focused on the United States. In 1931, he received considerable support for his views on counter-cyclical public spending in Chicago, then America's foremost centre for economic views alternative to the mainstream. However, orthodox economic opinion remained generally hostile regarding fiscal intervention to mitigate the depression, until just before the outbreak of war. In late 1933 Keynes was persuaded by Felix Frankfurter to address President Roosevelt directly, which he did by letters and face to face in 1934, after which the two men spoke highly of each other. However, according to Skidelsky, the consensus is that Keynes's efforts only began to have a more than marginal influence on US economic policy after 1939.
Keynes's magnum opus, The General Theory of Employment, Interest and Money was published in 1936. It was researched and indexed by one of Keynes's favourite students, later the economist David Bensusan-Butt. The work served as a theoretical justification for the interventionist policies Keynes favoured for tackling a recession. The General Theory challenged the earlier neoclassical economic paradigm, which had held that provided it was unfettered by government interference, the market would naturally establish full employment equilibrium. In doing so Keynes was partly setting himself against his former teachers Marshall and Pigou. Keynes believed the classical theory was a "special case" that applied only to the particular conditions present in the 19th century, his own the
