我们有很好的税收制度，但它并不完善,因为它并非完全从风险管理的角度,经过考量而得出的。

It doesn't work so easily to share with those people along the lines that these communities--I think these communes tend to emphasize a social compact, a feeling for each other, a caring for each other, which is a lovely thought but it doesn't achieve risk management on a big scale.

但要实现跟满足这些条件的人分摊风险,绝非易事,这些共同体。。。我指这些公社,倾向于强调一种社会凝聚力，一种人与人的深情和关怀，这个想法听上去很美,但无法实现大规模有成效的风险管理。
