True, but he also does say this:
14. The contention, then, that the civil government should at its option intrude into and exercise intimate control over the family and the household is a great and pernicious error. True, if a family finds itself in exceeding distress, utterly deprived of the counsel of friends, and without any prospect of extricating itself, it is right that extreme necessity be met by public aid, since each family is a part of the commonwealth.
"Extreme distress", "UTTERLY deprived", "extreme necessity".
So we adopt economic statism, tax the crap out of people, destroy work through regulations, make it basically impossible to have true Catholic hospitals, and Catholic relief societies because the government is sucking up all the tax money. So the poor no longer are helped by the local community, and we say, "See, Pope Leo is all for getting the State to help these people".
That's your point? Seriously?
So in a society where you have Catholic charitable hospitals and Catholic relief, how are people "utterly deprived"?
If you visited a few poor cities in this country you would see extreme necessity.
My point, however, is that discussion of governmental solutions is based in prudence. So far in this thread you've equated economic help and the State as socialism, full stop. Obviously this is not a principle seen in the actual papal texts. On the contrary, the Church speaks explicitly about the possibility of State help and guidance. So, by all means, you may argue that
this particular circumstance is decidedly not the one referenced in
Rerum Novarum, and to act as such would be greatly imprudent. However, to just go around labeling people who do espouse it in this particular circumstance as "socialists" is to ignore the papal text and to dogmatize against that which is in them as an approved principle.
