Success is relative to an individual. I don't think Hana Macchia is worrying about what grenskul on KF thinks of her financial situation if she herself is happy doing what she's doing, can eat, has a roof over her head etc. Some people would be perfectly fine earning minimum wage if it meant their full-time job was playing their favourite video games and meeting new people.
On the contrary, creating a hard, objective baseline of what 'success' is, and using Hololive as that baseline means that anyone who isn't pulling avg Hololive number is a failure, which is the single most anti-consumer, monopolistic mindset imaginable for an industry that began 3 years ago.
