Policy change will continue to happen. And they happen because someone is rooting for them. You can't penalize a Industrialist for being an Industrialist. They are wealth generators and are doing that for a large number of people and not themselves alone (you can argue by how much).

BTW, Farmers have enjoyed their share of handouts which are more or less treated as entitlement now a days: 1. Tax free income 2. Subsidies, lona waivers, electricity bill waivers 3. Minimum Support Price for the longest time
