Or what about Britain's history of horrific poverty that formed the basis for nearly all of Dickens' work. Germany's far more recent history, especially for those on the East side of the wall. Russia's treatment of its poor during and after Communism. The way that people just ignore the poor, and even dying around them in China, and India, without even taking a few seconds to call emergency services.
Which country has contributed personnel to every major UN mission? Which is the only country to have provided medical assistance, food, and logistics support after every major terrorist act or natural disaster through January 2017? Which country sends more volunteers around the world to house the poor, feed the hungry, and teach the children than nearly every other nation combined? (Hint: the answer to all of these is the US.)
But sure, only Americans only think of themselves...
