The movie in question is Vanilla Sky. The actual line is, “What’s ‘happiness’ to you, David?”
Raising donations to pay for drugs, or anything else for that matter, is perfectly fine by me. In a way, one could consider medical insurance to be one way of raising donations for such things. Giving or (more preferably, IMO) lending land and/or labor is a similar means. Of course, one can’t give or lend something which he doesn’t already own.
Your dad is right. My dad said something similar: “Life isn’t fair.”
