*I doubt very much if your friend's daughter was told that by any decent lecturer, using those words. It's your friend's daughter's interpretation*. Really growstuff? You weren’t there so you can doubt all you like, in much the same way I ‘doubt’ much of what’s claimed on these threads.
What 'claims' do you doubt, tickingbird?
I agree with growstuff that it is highly unlikely that a qualified lecturer would use the term 'lower classes' or say that they didn't have the same standards (as whom?). Both 'lower classes' and 'standards' are very vague terms that are meaningless in any academic context, and that sort of generalisation is, again, most unlikely to be used in a lecture, particularly one given by someone who has had a career in social work.
I can imagine there being a caution to the students against imposing their cultural norms onto clients and making assumptions about them based on whether or not theirs are the same, and I think that makes sense.
Whether someone is in their dressing gown at lunchtime or not is not an indicator of the likelihood that they will abuse their children, and nor is the tidiness of their house. Again, that is not the same thing as saying, in fact or implication as 'the lower classes have different standards'.
