The Pope is concerned for the good of humanity. The way globalization has been going has not been completely good morally. People with short memories may forget that the Pope was a major figure in the destruction of the Soviet Evil Empire. He sees that communism is evil. The Church also teaches that socialism, modernism, and communism are systems that are contrary to Church teaching. So the Pope is coming from that world view. There are plenty of conservatives who aren't completely libertarian (small "l") or objectivist in thought when it comes to the market, but their conservative credentials aren't questioned for the most part. The way some of these market purists are acting, they would be condemning Jesus for being a "socialist."
