Zenit: Holy See on Economic Crisis

"The Real Crisis Does Not Appear to Be Merely Financial"

No statement on usury. But there is this observation:

A third, and perhaps even more basic, observation has to do with the general public and its choice of values and lifestyles. A lifestyle, and even more an economic model, solely based on increased and uncontrolled consumption and not on savings and the creation of productive capital, is economically unsustainable. It also becomes unsustainable from the standpoint of concern for the environment and, above all, of human dignity itself, since the irresponsible consumer renounces his own dignity as a rational creature and also offends the dignity of others.

An explanation of what government is:

Government is the exercise of the virtue of prudence in the enactment of legislative and executive measures capable of directing social activity towards the common good. The principle of subsidiarity requires that governments and large international agencies ensure solidarity on the national and global levels and between generations.
