It is only in the last couple of centuries that we saw the possibility of actually increasing our goods and resources, and this is called capitalism. Its many good aspects have helped countless people to have the necessities of life and even comforts. It has also allowed a small number of people to have excess and luxury that surpasses anything available to even kings and queens in previous empires.
Our present capitalistic world view is based on an assumption and goal of constant and never ending growth (GNP), which is, of course, logically impossible on a limited planet of limited resources. Those of us born into this capitalistic period have taken it as the only pattern.
Limits should be just common sense but, then again, we tend to be blind when it comes to our own self interest. Logically and sustainably, we cannot just keep expanding, growing, and consuming. We must return to lives of humility, simplicity, and limits (“justice for all”) which is what the Gospel said all along.
