I feel that Harshad must have been kicked out for money and status reasons......since he always keeps saying that money is not everything and Baa was listening with a smile.
I think Harshad's wife must be from a rich family and must have insisted that they take help from her father which Baa must not have approved.
I also think that the difference in Harshad and his brothers must have been a lot due to education, earning and lifestyle... which is why Baa must have separated them all.
Any comments?
