The negative effect of income inequality on economic growth represents a topic that constitutes a broad topic of research in the standard economic theory. One of the immediate consequences of income inequality is diminished consumption. Many «poor» customers cannot provide sufficient demand for the producers, causing overproduction that might lead to an economic crisis. It constitutes a problem because sustainable economic performance needs to be achieved under the conditions of income inequality. Reducing social and economic inequality in countries is an essential step towards ensuring that no one is left behind. It is also part of the 10th Sustainable Development Goal aimed to reduce it by 2030. Inequality is based on the income distribution between the top 1% and the bottom 99% of households in any given country. The degree of inequality could play a beneficial role if it is driven by market forces and is associated with incentives to increase growth. In developing and emerging countries, greater equality and improvements in living standards are needed to enable populations to flourish. Inequality reduction is one of the most critical steps a government could take to improve the well-being of its population. The income inequality growth increases human capital in poor countries and reduces it in high and middle-income countries. In poorer countries, it increases them, but in higher – and middle-income countries, it reduces them. Income inequality could be reduced by improving human capital and general skill levels, correcting labor-market policies, and making better use of financial services. In turn, sustainable economic growth could reverse the negative effects of inequality, reducing the need for high-wage and higher-earning households. Thus, it provides higher economic growth. This paper discusses three ways to circumvent the impact of decreasing consumption on economic growth adopted in developing economies over the last fifty years, such as increasing exports, providing loans for consumption, and printing new money. The findings showed that none of these methods seem to be sustainable in the long run. Thus novel and innovative mechanisms that would allow our economy to reduce inequality are necessary and need to be put into place.
