It is obvious to me that most radical comments against this document are by those who have not read the long series on this subject of good stewardship. I posted the long list of encyclicals, and parsed out years ago Caritas in veritate for my readers.
Someone on another blog objected to the word redistribution, as if Francis was the first to use this.
Not so and here is one example from the Pope Emeritus.
36. Economic activity cannot solve all social problems through the simple application of commercial logic. This needs to be directed towards the pursuit of the common good, for which the political community in particular must also take responsibility. Therefore, it must be borne in mind that grave imbalances are produced when economic action, conceived merely as an engine for wealth creation, is detached from political action, conceived as a means for pursuing justice through redistribution.
And a repeat link for an important list of encyclicals...
