John E. Ikerd argues that sustainable capitalism is needed based on common sense principles. He believes that neoclassical economics and unrestrained capitalism lead to the exploitation of people and resources for selfish gain, undermining social well-being and happiness. Sustainable capitalism should be based on classical economic principles of pursuing happiness through caring relationships with others and future generations, rather than just the pursuit of wealth. It requires managing the economy in a way that meets current needs without compromising the ability of future generations to meet their needs through ethical treatment of all stakeholders, environmental stewardship, and a balanced approach that considers both economic and social factors.
