Who they are

An English economist and founder of macroeconomics. Facing the Great Depression that swept the globe in the 1930s and left classical theory helpless, he offered a subversive prescription: in a recession the market cannot heal itself, and the government should step in actively, stimulating demand and creating jobs through greater spending and investment in public works. His line "in the long run we are all dead" was precisely a biting rebuttal of the counsel to "patiently wait for the market to cure itself." Keynesianism went on to become the mainstream theory behind Western governments’ intervention in the economy, profoundly shaping the economic policy of the entire postwar world — he fitted the market with a "visible hand."

Key stories

"In the Long Run We Are All Dead"

When classical economists offered the comfort that the market would recover on its own, unemployment would eventually vanish, and one need only wait patiently, Keynes shot back with a line still quoted today: "In the long run we are all dead." His meaning: in an economic crisis, people are going hungry and losing their jobs — they cannot afford to wait for that distant "long run." The government must act now. It was this biting rebuttal that turned "active government intervention in the economy" from heresy into mainstream, and reshaped how the entire modern state responds to crisis.

The "bailout" logic in moments of crisisAt every major economic crisis (the 2008 financial crisis, the pandemic shock), the large-scale stimulus and bailouts of governments use Keynes’s logic of "government managing demand" — the saying "we are all Keynesians now" recurs again and again.
