Yes, what this man did is very effective in fighting the caste system. It ingeniously breaks through a system that's been around for far too long and is unfair and unjust. By empowering himself and his entire village by taking action and digging his own well, he's made more strides against an unfair system than any other protest would have achieved.
It is one way to fight the caste system. It is certainly making a change for these people. Unfortually not everyone has the time or the energy to build wells or otherwise solve the problems that the lower caste people face. There is a lot more that needs to be done.
Even if a Dalit scavenger can afford to buy a cow and sell milk or open a shop, for example, upper caste customers are unlikely to buy any of the produce.
In Amit's village Ladwa, like in most of India, no Dalits own land although his friend Vimal has moved into a house he bought from the upper caste members.
It's a spacious, solid building but the neighbourhood has changed.
As Dalits moved in, all upper caste neighbours moved out, so the prices have really come down. that discrimination is not limited to the upper caste, within the Dalit community there are many sub-castes and hierarchies.
The most effective way to fight the caste system is through education. People who promote these views need to understand that we are all human, worthy of equal respect and deserving of equal rights. These antiquated views have existed for centuries and it will take time to change but this can happen through educating the younger people.
