People genuinely want to pitch and help others. Maybe some of that is based in the service requirements many middle and high school students must fulfill to be eligible to graduate. The culture of service is a little more ingrained now.

The levels of service today haven't been seen since Pres. Kennedy made his famous "Ask not what your country can do for you but what you can do for your country" speech.
