It looks like your sentence was cut off, but I'll try to help you complete it or provide relevant information based on what you have.

If the sentence is meant to be about jokes regarding people in Los Angeles, it might be completed like this:

"People joke that no one in Los Angeles actually has a job; they're all just trying to become an influencer or a movie star."

However, without more context, it's difficult to know exactly what kind of joke or statement you're referring to. If you have a specific topic or completion in mind, please feel free to provide more details!
