> Catholic church that pushed people to reproduce without limits

It's hard not to interpret this as just garden variety bigotry, of the same sort that caused the famine in the first place.
Let's assume it's correct, though. The Catholic church had been one of the most powerful organisations in Europe for well over 1000 years by the time if the famine. Why did it take until Ireland in the 19th century for their population mismanagement to become truly problematic? Also why did this not also happen in a country like Spain? Hard to find many more enthusiastically Catholic countries than Spain in that time period.
The population density of Ireland at the time of the famine was comparable to England (it is now much lower). Ireland produced enough food to feed itself and millions of people in English cities at the time of the famine. The issue was not a lack of food but the "ownership" of the food.
The account of capitalism emerging from the black death is a fine theory for continental Europe. At the time of the black death, Irish society was controlled by Irish people. After the 1600s it was increasingly run as a colony, with the indigenous culture outlawed and intensive resource extraction for export to England (timber, food, etc).
You might as well ask why industrialisation didn't take off among the Choctaw or the Cherokee. Or maybe they also just have the wrong religion?
