The relationship between markets and morality has been the subject of analysis and sometimes intense debate for centuries, since Aristotle wrote chapter 1 of The Politics and possibly sooner. I myself have participated in many of these debates, and the position I would typically take is that markets were either amoral at best, or a cause of vice at worst. There are many Catholics and many Distributists who probably share the same view. They will concede and even embrace the fact that the Papacy has not categorically condemned market activity, but they will spend the majority of their time highlighting why markets ought to be regulated and taxed, why we need welfare programs, labor unions, and all of the rest.
I have written extensively against a phenomenon called consumerism, which is also heavily critiqued in the Papal encyclicals. But it would be wrong to associate consumerism, which is a byproduct of mass production and communications technology, with market activity as such, since it pre-dates industrial society by thousands of years.
