International Monetary Fund on income inequality

See their full June 2015 report here. The executive summary notes that income distribution to the top 20% does not trickle down and leads to economic stagnation or recession. Rather a higher income distribution to the bottom 20% will stimulate the economy. Also "better access to education and health care and well-targeted social policies, can help raise the income share for the poor and the middle class." Now whose policies favor the above? It certainly isn't the Republicans or Trump.
