Even if one thinks narrowly about one’s own descendants, presumably one hopes that they will be thriving in, and making a positive contribution to, their future society. Assuming that they are significantly better off than one’s own generation, how important is their absolute level of income?
即使你只关心自己的后代，当然你希望他们能够发达，并能为未来社会做出贡献。假设他们比你这一代的福利要好得多，那么，他们的绝对收入水平有多重要？
