I think wealth inequality matters, but not only from a moral standpoint: From wikipedia on Trickle-down economics: > A 2015 report by the International Monetary Fund argues that there is no trickle-down effect as the rich get richer: >> [I]f the income share of the top 20 percent (the rich) increases, then GDP growth actually declines over the medium term, suggesting that the benefits do not trickle down. In contrast, an increase in the income share of the bottom 20 percent (the poor) is associated with higher GDP growth.[19]
