I think you’re right...”wild capitalism” is not “capitalism”.
True capitalism is an outgrowth of the Judeo-Christian ethic.
Remember, the forces of evil pervert EVERY good thing...
But the question is — what did the person who made this statement (either the pope or the governor of BA) mean by his statement?
Given the fact that there was a Papal Encyclical against Socialism way back in 1878, that Pope Francis didn't go along with the "Liberation" theology crowd, and that Socialism by definition contradicts several Doctrines of the Church as well as several other Papal Encyclicals, I think it's clear that when a Catholic uses the term "wild capitalism" they're talking about excesses, not all Capitalism or Capitalists in general. They're talking about the sort of capitalism that dope dealers and child pornographers are practicing, Capitalism as practiced by predators of all sorts with no regard for the consequences of their economic actions.
While those may be extreme examples, is it really all that difficult to understand that there are a lot of things done in the name of capitalism that contradict Christian values? NO, it isn't at all difficult to understand, in fact, it's really simple. Saying, "the market made me do it" isn't an acceptable excuse for abusing your fellow man by ignoring the consequences of your actions any more than "class struggle" is.
It's very hard to believe that folks who insist the Holy Spirit guides them individually to an unerring understanding of Scripture can't figure out what "wild capitalism" means in light of Scripture and nearly twenty centuries of Catholic teaching.
Of course, there are dedicated anti-Christ propagandists who "fail to understand" whatever they figure they can use to further their agenda of fostering squabbles among Christian and who don't care about the Holy Spirit to begin with. They're the sort who only care what they can claim it means just like some wolves disguised as sheep within the Church only care what they can claim something means.
Whether playing the role of an anti-Catholic or playing the role of a faithful Catholic, folks who strive to distort fairly obvious meanings into something that fits their agenda are children of the father of lies.
