Apart from the money, Islam had no reason to live in Gurgaon, and that's why he and his family returned home. Of course, he earned a little bit more money in Gurgaon, but the cost of living in Gurgaon is much higher than that in his hometown.
As for farming, I agreed it's a great occupation and one that is necessary (even though I came from a rural community in Canada, and was glad to escape it. ☺ )
Unfortunately, the big agri-biz / seed / fertilizer companies have had a deleterious effect on farmers in India, to such an extent that many farmers can hardly make a living for themselves and their families.
(And just recently, I've heard there's a similar horrible trend in the US. Sad)
The state of farmers is very bad. However I believe this is happening because they are not educated. If they get proper guidance and if our governments are not corrupt they will do really good. What the politicians are forgetting here is if the farmers fade away, we will have no food to consume :(
