The thing is, what constitutes a living wage is based on the home location, and all other wages reflect to that level. Most of the wages go to the cost of living everywhere, especially to housing. There is the leeching class, landowners, leeching the fruit of labor from the workforce, and in the west they are leeching that much more in pure dollars. The sad thing is that wages increasing in India wouldn’t go to increasing the value of life of the workforce, but the landowning leeches of that region.
The protagonist claimed to have been wrongly imprisoned. That’s one of the greatest hooks of the film imo, we the audience want to believe he was innocent, but if looking at the case objectively, he could have been guilty as well. I would even say it was probable. Andy even admits he went to confront his wife, armed and intoxicated, but claims he fell asleep on the driveway, while some other guy went into the house and did the killings. With the same type of bullets his gun used, which also mysteriously disappeared from his possession.
