Because Keynesian theory has triumphed in the economics world, people are subject to the worst kind of government intervention in the economy. Debunking Keynes is the first step toward economic sanity.
When an economy suffers a recession, some factors of production, such as labor, become unemployed. Keynesians believe that expanding credit and fiat money will bring back full employment. That's not how an economy works.
Advocates of unbacked paper money claim that theirs is the “civilized” choice, as opposed to gold, or what Keynes called “that barbarous relic.” These inflationists, however, are the ones wrecking civilization as we have known it.
