Why do successful actors think they are smart enough to save the world and have the answer?

Those of us who lived life, fought for our country in BS wars around the world, raised children on a meager salary, sacrificed for our kids education and worked ourselves to physical exhaustion find that we are lectured by Martin Sheen, Alex Baldwin, Kathy Bates, Brad Pitt, Sean Penn et al. They tell us how to save our planet, raise our kids, accuse us of racism and then fly back to their mansions.
