Capitalism isn’t really an ism.
Capitalism is what happens when people are free.
Which means the Catholic Church SHOULD support it.
Unfortunately, there is a long tradition of bishops and priests having absolutely no clue when it comes to economic activity or human freedom.
I agree there is a lot to be said for ignorance, especially in the clergy. saying capitalism is not an “ism” is however, a syncretization of separated ideas. These things may compliment each other, but economics is certainly not metaphysics, or politics, or morality, or anthropology.
What you claim to be capitalism is another philosophy.
