So says the headline in the Washington Post this morning. And one thing that an increasingly multiracial and multiethnic United States cannot have is a system in which its institutions treat people differently according to skin color and what country someone’s ancestors came from — where, for example, public universities and government contracting officials give preferential treatment to some and discriminate against others on the basis of race and ethnicity. Such division was never a good idea and is now simply untenable. E pluribus unum — now more than ever.
