Could Harry Potter Change the World?

After the first weekend, Harry Potter and the Deathly Hallows Part 2, took in $168.55 million.  Imagine what good things could be accomplished if each one of those ticket holders donated 1/2 the cost of his/her ticket to charity. Or, if they can't part with their money, perhaps the ticket holders could donate their time to community service--1/2 of the running time of the movie.  Money or time?  Some say time is money.  Regardless, the moviegoers invested time and money in Harry Potter. Would they do the same for the homeless, the blind, the elderly?  What about you?
