Free Market Capitalism has given billions to the Catholic Church. It is Catholics like Joe Biden , the Kennedy family and Pelosi who think the mass middle class should pay more taxes for the poor while they enrich themselves with government influence.
It is a matter of balance, which both sides are liking. One side says that if it drives up profits, no matter what, it is good. One says that all property is theft, and all wealth belongs to those who don't have it.
Both are condemned explicitly in traditional Christian theology. Both are very popular heresies today.
Now, I am not a Catholic. I honestly started looking into the Catholic views because of my mother in law, who is in favor of something called “Christian Socialism” (Distributism under a different name). It isn't quite what it sounds like (for instance, it isn't true socialism, there is private property, but a body controls how much of a given market you can have), but it has the same issues that all systems have. Namely, it will only work if the people in power are angels.
This view is why many religious Catholics feel compelled to vote Democrat. As they move farther down the abortion/ eugenics road, more of them are moving to the GOP. And they are trying like mad to pull them to the left on economics.
It is a situation that seems (to me) like a recipe for a third party. A socially conservative but fiscal liberal party.
