“…Inequality has continued to widen all over the world, and has even reached its historical maximum level in some countries in the last few years (Zalewski and Whalen, 2010;Piketty, 2014;Haan and Sturm, 2017;Westcott and Murray, 2017;Bolarinwa et al, 2021). This translates into a great scourge for contemporary societies because of its deleterious effects, which include the following: the spread of destitution, criminality, corruption, injustice, insider privilege, unequal opportunities and social-political unrest (Tan and Law, 2012); hunger, poor health and a fall in life expectancy at birth (Claessens and Perotti, 2007;Bolarinwa et al, 2021); the rise of abstentions in elections, the proliferation of populism, the emergence of more extreme political parties, the recurrence of more defragmented parliaments and the absence of political majorities and, consequently, less political stability; the growth of the informal sector (Claessens and Perotti, 2007); a decrease in entrepreneurial activities and consequent harmful effects on labour productivity and on productive investment (Claessens and Perotti, 2007); weak economic growth and an increase in unemployment, due to higher levels of taxation to implement public policies to mitigate inequality (Seven and Coskun, 2016); the recurrence of episodes of financial and economic crisis due to the greater indebtedness of poorer people as a way to overcome their stagnant wages and maintain their consumption standards (Haan and Sturm, 2017;Romão and Barradas, 2022); and even climate change.…”
