Co-op type arrangements are plausible in many areas. I heard about coops - groups of Christians who don’t have their own health insurance provided by an employer - forming an association that self insures the members, collectively. None of their “premiums” goes to shiny glass buildings and paid advertising (let alone abortion).
Ave Maria Funds is a pro Catholic, prolife family of mutual funds. They invest only in companies that are compatible with Catholic social teaching. This is a way of “bundling” your retirement savings with others. This is a tiny mutual fund family, but still much bigger than you or I personally.
These are only stop gap solutions, but necessary, to deal with the massive centralized corporations (including the federal government, the biggest corporation of them all). In the long run, we have to work towards distributism, which is found in Pope Leo XIII teaching but developed by G. K. Chesterton.
Support self employment, or small businesses. If a given manufacturing process requires a group of workers, let the workers in this particular factory collectively own this plant, and no other plants. Government should be handled at the lowest level possible with the task. When economic decisions are centralized as they are now, they invariably move not only farther from individual choice and freedoms, they move farther from any kind of morality.
The short term goal is to form cooperatives to help deal with corporate goliaths, the long term goal is eliminate the corporate goliaths.
