Social mobility is high and allows people to adapt to changing economic conditions.
Is Good for the Poor done by two economists at the World Bank, David Dollar and Aart Kraay. The rich are getting richer, the poor are getting poorer. Indeed, one broadly held view is that economic growth does not benefit the poor. The revenue of the poor might not increase at all or not increase as fast as that of the rich, so that economic growth would create more inequality. Even at times of strong economic growth and reduced unemployment, poverty remains a pressing concern.
