I agree with her for saying models should have general knowledge but don't agree with speaking English. It's not just models, an average human being should have basic general knowledge and that has nothing to do with educational qualification. A lot of older people with not much higher education will have way better general knowledge than a young graduate.
Iman herself don't look like someone who speaks good English. I don't know much about her except seeing two three clips from her IVs and in all of that she was speaking Urdu. Then through reddit I got to know she used to date imtiaz ali for 7-8 yrs
Some other senior model who might be in her 40s also said something similar about young models and she was much more demeaning. I guess she said nowadays models come from middle class and lower middle class families and they don't have class or something like that.
