What's about "celebrities" that get so much attention?

if you think about it like that, it's kinda hard to answer clearly. Well, i don't know it's mostly musicians that try to grab people's attention by doing crimes and obnoxious behavior, they don't deserve this attention, fans are just giving it to them. Celebrities just act in favorite movies and sing some favorite song, which creates people's attention to follow everything they're doing in they're career. Professionals that create most of the technology today and helped us in our hospitals with trying to cure cancer, deserve the attention, they help us all, what are celebrities going to do for us? celebrities aren't thankful for what they have, they just expect it coming to them.
