Recent history has shown that we can’t be sure that economic expansion alone will solve our wider economic problems. Almost all of the benefits of economic growth during the past 30 years or so have accrued to the rich, and mostly to the super-rich. Real income for most people has been stagnant or even declined. The new jobs that have been created are mostly temporary, low-wage, no-benefit jobs. Permanent, good-wage jobs with benefits have continued to disappear. Rather than giving money to the rich in these circumstances and hoping that it trickles down to the rest of us, as the supply-siders suggest, it would be better to give money to the poor and middle-class, as the Keynesians suggest. The Keynesian approach, after all, has worked many times in the past. Indeed, it’s how the West emerged from the Great Depression. But most importantly, if for some reason it doesn’t work, at least we will have made the right people better off.
