Market mechanisms have lifted many out of poverty. They have also left millions behind as a result of unrestrained greed, excessive materialism and massive inequality. The Tribune editorial has nothing to say about that. The Catholic Church does. It is unswerving in its conviction that we must make sure our markets build an economy for all and do not accelerate injustice and grave inequity. In this time of globalization and dominant and often unaccountable financial institutions, we need to bring together technical knowledge and human wisdom. In Catholic thought, moral principles must guide the market. Protecting human life and dignity comes before the unlimited pursuit of profit. This is a vital and timely message for a divided world — and Chicago.
