Nobody here has the opportunity to be Bojack, a large portion of his character and the way it develops is because he’s rich and famous. A couple quotes to consider:
“Diane, I am a famous — everyone gives me everything I want all the time. It is an existential curse, but a huge day-to-day convenience.”
“I’m at a place right now where I never need to grow as a person or rise to an occasion because I can constantly just surround myself with sycophants and enablers until I die tragically young.”
The trappings of fortune and fame are a huge factor in character development.
It has light in the middle of the tunnel.
