The ex-T4 presenter, whose US show It's On With Alexa Chung was axed in December, suggested to Radio Times that American producers are not used to dealing with opinionated young women.
Chung said: "They don't have the tone that T4 has anywhere in American TV. If you're a girl and you're my age, you're on a shiny night-time show and you've got your boobs hoiked up and you're not really giving opinions. You're merely a conduit.
"Sometimes I'd be in the middle of interviewing - insert starlet's name here - and I'd aim to have a joke and be irreverent, and then it would transpire that they weren't getting it and I had to switch back and do a straight interview."
She added: "[Channel 4 was] like being in sixth form and calling your teachers by their first names. You know, executives that you go bowling with. Whereas at MTV, people sit in their offices and don't come down."
Chung reportedly insisted on recording her Channel 4 return Frock Me in New York.
