回答: I doubt the rich people live significantly longer than the poor ones 由 HunHunSheng 于 2005-6-15, 15:32:09:
It's more important in terms of proportion.
Say the poor lives to 70 but the rich 73. That means the poor receives 3 years benefit which the rich 6 if the benefits start at 67. Therefore an extra 3 years, which is not significant, results in twice as much the benefit, which is very significant.
