Adam Smith addressed the question of whether vast inequalities of wealth represented progress. He explained that the wealthy often demand convenience, employing numerous others to carry out labor to meet their demands. Smith argued that this allows wealth to be redistributed among inhabitants, and for all to share in progress of society. Smith explained that social forces could regulate the market economy with social objectivity and without need for government intervention. Smith regarded the division of labor as an important factor for economic progress. John Millar suggested that improved status of women was important for progress of society. Millar also advocated for abolition of slavery, suggesting that personal liberty makes people more industrious, ambitious, and productive.
