"According to the IMF, countries looking to boost economic growth should concentrate their efforts on the lower segments of society rather than bolstering so-called 'job creators' with tax breaks. The study results suggest that raising incomes for the poor and middle class yields measurable improvements to the national economy: Increasing the income share to the bottom 20 percent of citizens by a mere one percent results in a 0.38 percentage point jump in GDP growth. By contrast, increasing the income share of the top 20 percent of citizens yields a decline in GDP growth by 0.08 percentage points." -- Jared Keller, "The IMF Confirms That 'Trickle-Down' Economics Is, Indeed, a Joke", 2015-06-18
