But taking a serious look back … I do have one big regret.

但是，如果现在严肃地回忆起来，我确实有一个真正的遗憾。

I left Harvard with no real awareness of the awful inequities in the world – the appalling disparities of health, and wealth, and opportunity that condemn millions of people to lives of despair.

我离开哈佛的时候，根本没有意识到这个世界是多么的不平等。人类在健康、财富和机遇上的不平等大得可怕，它们使得无数的人们被迫生活在绝望之中。

I learned a lot here at Harvard about new ideas in economics and politics. I got great exposure to the advances being made in the sciences.

我在哈佛学到了很多经济学和政治学的新思想。我也了解了很多科学上的新进展。

But humanity's greatest advances are not in its discoveries – but in how those discoveries are applied to reduce inequity. Whether through democracy, strong public education, quality health care, or broad economic opportunity – reducing inequity is the highest human achievement.

但是，人类最大的进步并不来自于这些发现，而是来自于那些有助于减少人类不平等的发现。不管通过何种手段——民主制度、健全的公共教育体系、高质量的医疗保健、还是广泛的经济机会——减少不平等始终是人类最大的成就。

I left campus knowing little about the millions of young people cheated out of educational opportunities here in this country. And I knew nothing about the millions of people living in unspeakable poverty and disease in developing countries.

我离开校园的时候，根本不知道在这个国家里，有几百万的年轻人无法获得接受教育的机会。我也不知道，发展中国家里有无数的人们生活在无法形容的贫穷和疾病之中。

It took me decades to find out.

我花了几十年才明白了这些事情。
