i agree with that article person the book is about many things
1) Self discovery of a person
2) How society in those times treat good people like Saras(including family)
3) A person's progressive thoughts like Saras wants a model village where rich serve and share with poor
4) A son sacrificing his happiness for family
But these ideals are not relevant in today's money minded cut throat competition days. Today only money and success at any cost matters. How else will you explain people respecting rich people who have made money by dubious means cheating others?
In 18th century atleast to some extent a persons good nature counted more than his money and status not in 21st century. In today's fast paced world TV aduience is not intersted in seeing an ideal hero who talks of right and wrong and improving others life. Hence SLB knows that and is giving love angle to the story so that he can retain audience interest. If SLB goes by that book TRPs will fall drastically. SLB should disguise messages that Saras wanted to give to society around a love story.
