Often, during my stay in your country, such comparisons troubled me. In fact, they did more than trouble me: they made me resentful. Four thousand years ago, we, the people of the Indus River basin, had cities that were laid out on grids and boasted underground sewers, while the ancestors of those who would invade and colonize America were illiterate barbarians. Now our cities were largely unplanned, unsanitary affairs, and America had universities with individual endowments greater than our national budget for education. To be reminded of this vast disparity was, for me, to be ashamed.
