Yes, they (government) should provide better housing and all other necessary facilities to people living in slum areas.
But the actual question is whether India is capable of providing housing facilities to all the people living in slums or not? With the corruption and population growth rate at hike the condition that we might see in future will be more than worst than that we’re seeing now.
I agree with both of you that their should be at least an initiative for providing good housing facilities. Even though if we make it to provide 20% of the slums a better housing, it will after all contribute to the whole economy of the country.
