why?

Why do celebrities donate a few million to their charity of choice and is then broadcasted over the media for the next 72 hours nonstop. And what I don’t get is these so called celebs donate 1, 2 million when they make $20 mil a picture. $1 million is like $10 dollars to them. Why are we not praising our troops and their families who are fighting for us and sacrificing being away from their families for us? Instead, we hear about so and so donating poket change. Just sayin what everyones thinking.
