Your thoughts apply to all the Indian serials not just KS. They all have characters that are educated but seem to have not progressed socially. There are two wives, siblings, parents and relatives etc back stabbing or wishing ill to their own brother, sister etc.
I have been to India and know even in small towns the people may not have degrees but you know they have positive attitudes to daughters and daughter-in-laws. I think KS team and other serial producers really need to change the way they are creating storyline to show healthy relationships, realistic plots and teach them that having a disabled child, unwanted pregnancy or having daughters is not misfortune in life. The TRP's of the show really shows what the viewer thinks of the storyline.
