"Somewhat unusually for the growth literature, studies have tended to concur in
finding a negative effect of high inequality on subsequent growth. The evidence has not been accepted by all: some writers point out the concentration of richer countries at the lower end of the inequality spectrum, the poor quality of the distribution data, and the lack of robustness to fixed effects specifications. At least, though,
it has become extremely difficult to build a case that inequality is good for growth. This in itself represents a considerable advance. Given the indications that inequality is harmful for growth, attention has moved on to the likely mechanisms.... the literature seems to be moving ... towards an examination of the effects of inequality on fertility rates, investment in education, and political stability.
