Are free markets an anathema to Catholicism?
Here's a book review from Tom Woods (I haven't read the book being reviewed): https://mises.org/journals/jls/19_4/19_4_8.pdf
Here's an essay from Woods himself: https://mises.org/pdf/asc/2002/ASC8-Woods.pdf
Other Catholics, too, seem to grasp the importance of contributions to humanity from Mises: http://catholicexchange.com/where-have-you-gone-ludwig-von-m...
My favorite is Rothbard's take. Try the first several chapters of his masterpiece History of Economic Thought: http://mises.org/books/histofthought1.pdf
Of course, on the other side of the debate there is literature that I, for one, consider to be obvious NWO propaganda, such as: http://www.amazon.com/The-Poisoned-Spring-Economic-Libertari...
The gist of that book appears to be: "You will go to hell if you don't consider your brother first and foremost." Remember the French Revolution, though, with all those Jacobin Club socialists running around murdering left & right and saying to their fellow (Catholic) Frenchmen: "Be my brother or I will kill you" (a real motto of the people perpetrating that terror).
Fortunately, people aren't always so quick to obey the collar, as comments beneath this drive-by dismissal might indicate: http://catholicism.org/ludwig-von-mises-and-catholic-social-...
Concluding opinion: I'm afraid that the Catholic Church, like so many other institutions in these "modern" times, has been overrun by what can only be described (in torah terminology) as luciferians.
