But America's race problem is increasingly one of class.

但是美国的种族问题日益突出远不止如此。

I was not smart enough to perceive that it was an American problem until much later when race problems became dominant in this country.

我还不够聪明，没有意识到这是美国的问题，直到很久以后，当种族问题成为这个国家的主要问题时，我才后知后觉。

William Du Bois had believed that education and knowledge could help solve the race problem. But racial prejudice in the United States was causing violence.

威廉·杜博斯认为教育和知识可以帮助解决种族问题。但美国的种族偏见引发了暴力。

Well, that's undoubtedly true. The large number of racially charged issues in the headlines of the last few years proved that the country's race problem is a systemic one. In other words, we all bear responsibility for dealing with it.

一点也没错。过去这几年来，报章杂志充斥着种族歧视报导，显示美国种族问题是体系上的问题。也就是说，所有人都该负责。
