When businesses and market economies function properly and focus on serving the common good, they contribute greatly to the material and even the spiritual well-being of society. Recent experience, however, has also demonstrated the harm caused by the failings of businesses and markets. Alongside their benefits, the transformative developments of our era globalisation, communication technologies and financialisation produce problems: inequality, economic dislocation, information overload, financial instability and many other pressures that interfere with serving the common good. Nonetheless, business leaders who are guided by the ethical social principles, lived through virtues and illuminated for Christians by the Gospel, can succeed and contribute to the common good. Obstacles to serving the common good come in many forms, corruption, absence of rule of Law, tendencies towards greed, poor stewardship of resources, but the most significant for a business leader on a personal level is leading a divided life.
