Those are good questions.  I suspect the economic one gives pause to some in "positions of authority" along with fear of not having enough followers to keep them in a "position of authority" in the manner to which they have become accustomed.   The impact of a true, worldwide schism -- not just a small handful splintering off without taking significant assets with them -- would be catastrophic, I think, both for the Church's missions and for countries with large Catholic populations and for leaders of government, society, or business who have essentially thrown their lot in with the Church or those they see as its representatives.  I suspect the impact would put the Reformation and Counter Reformation to shame, economically, though hopefully not as bloodily. 

But I also suspect a continuing drift away and personal missions while staying formally committed are more likely than formal schism.
