You're confusing interdependence with loyalty. The end game of the sangh is to consolidate power and money in the hands of a tiny minority - the upper caste Hindus. The big corporates just help them in that endeavor. The corporates do that because extreme right wing governments deflect attention of the populace towards communal enmity and away from their corruption, exploitation and wealth consolidation. This isn't a pattern unique to India - you can see it playing out all over the world.
