I have traveled and visited many countries and continents. This experience confirms the basic thing that defines the common good for all people. People just want to be able to live in security, with enough money (work) for shelter and food, to give their children a good education, and some discretionary income. Their desire is to have the freedom to work in an environment that allows you to have these basic things.
It is the responsibility of the government to create and sustain this atmosphere. Anything less than these basic requirements is a failure of the government. Thus, security and work for shelter, food, education, and discretionary income is the basic common good also known as dignity. This is all that anyone is looking for dignity! Self-respect via the respect of others and the ability to function responsibly in my domain.
“Any man or institution that tries to rob me of my dignity will lose.” Nelson Mandela
