Exhausted by World War I, the British economy was suffering from a severe depression with an unemployment rate of 25%. However, even in the face of this national crisis, the mainstream "classical" school of economics remained stuck in outdated values, insisting that "time will solve the problem." Keynes, a masterful economist and finance official, questioned this situation and came to a conclusion: "The reason recessions do not resolve according to economic theory is not because they are irregular events, 　but because economics itself has been left behind by developed societies!" Keynes devoted all his energy to developing an economic theory suited to modern society. This work, "The General Theory of Employment, Interest and Money," is now a standard economics textbook. This revolutionary work, which dramatically elevated economics from "modern" to "contemporary," is now available as a manga.
