What does "all about something" mean?
Native speaker’s answer
Rebecca
To be "all about something" is to be very interested or invested in a certain topic or thing. In this case, the speaker has used this informal expression to state that some CEOs only are interested in money, and not the job itself. Ex: My family is all about saving the environment. They avoid using plastic and bike everywhere. Ex: I'm all about the goth look. All my clothes are black, and I even wear black lipstick.
