Having studied Rerum Novarum and Quadragesimo Anno at some length, I would say that my simple answer would be that it is largely admirable goals, but probably very difficult to enact on a large scale.
For example, for the concept to work ‘means of production’ must be spread through the general population as widely as possible. But most economic theory points to pressures in the opposite direction. That is, economic systems naturally trend away from subsidiarity, at least as Pope Pius XI viewed it.
Take something as simple as health care. Because health insurance is largely provided by employers in the US and because health care itself is devestatingly expensive, many people who otherwise want to start businesses, cannot, because of pre-existing conditions, etc.
To me this is a good example of where the theory has some correct worries, but misplaced. Situations like above, where inalienable rights of the human person are placed in hands of employers, creates a variant of the “Servile State”. On the flip side, none of the predictions about US Social Security from either Dorothy Day or Hilaire Belloc have born out. In fact, the exact opposite has occured.
One of my largest qualms about distributionism is that it does not favor any particular political system/order. The Church now teaches that a constitutional democracy is the best form of government and I whole heartedly agree.
I’m sorry, I presumably either missed or missunderstood your question. I’d ask you to repharse it, but I’m only skimming these threads sporadically at best. If you would really like to understand the mortgage crisis, I’d suggest something like this:

When people are still thinking in terms of mortgages and buyers, then they are largely still in the dark about what transpired and why. Some of the financial instruments and dealings involved are so complicated that even the people who concocted them can’t clearly explain them. Although I could quibble with some particulars, I have to commend Blumberg and Davidson for doing an excellent job of explaining things like mortgage backed securities in a way that average people can understand.
