I have traveled almost everywhere, and I have found that there are essentially three categories of countries in the world today.In the first, people work all day and still don't have enough to eat.In the second, families are able to scrape together just enough food to meet their basic needs.In the third category of countries, diet books are bestsellers.Of course, the same distinctions also apply to the neighborhoods of Boston and Baltimore, and to the mountains of Appalachia and the American West.Confronted with this hard truth, some people simply shrug their shoulders and say that such inequality is too bad,but there is not anything that anyone can do about it.I say, such unfairness is intolerable, and we each have a responsibility to change it.As the "light on the hill," the Tufts community has always taken these responsibilities seriously -- and today's graduates are no exception.Through protests and marches, you have made your voices heard on behalf of the voiceless.You have stood up on behalf of workers, you have spoken out against the scourge of sexual assault,you have made clear that black lives matter and you have pressed for action on climate change.With the assistance of institutions such as Tisch College, you have shown yourselves to be active citizens
