Totally agree. It's a two-way street. The difference I think is that, in the past, you really had to "be" someone to be a celebrity. If Gary Cooper, or The Duke, or Marilyn walked down the street, anyone at that time would recognize them. Today, a celebrity can be pretty much anyone from online who is notorious. Especially with the advent of online presence. As opposed to actually having accomplished something. Years ago, extras my be added to a war movie just to get shot and see them fall. If lucky, they had one line. And then went back to their job at the hardware store. Today, they wonder why they're not the next Richard Burton.
I blame superhero movies . . .
