But thats wrong, and I can prove it.
In 2019/2020 (at least so far), Jamie has voiced 8 characters, and of those 8 maybe 2 are big roles (I'm not familiar with the materials she voiced, its possible I'm off by 1 or 2). Monica has voiced 10 characters, and of those 3/4 are main characters (would you consider Bulma a main character anymore?).
Small bit roles like 60% of their work has been does not pay the bills. Those roles are too small and don't last long enough. Jamie's big roles also aren't huge big roles, she has done better previous years. Monica might be able to survive off of her role in MHA, but I somehow doubt it. General consensus around the industry is that unless it's work as the main character, it's below living wages, and even then you aren't employed 9-5 365 days per year as one role.
So no, VA's need an alternative revenue source, you thick skulled perjuring caveman. No matter how many times you defend your waifu, she won't fuck you nor realize/care you exist.
