Colonization
No, I am not kidding
Basically, Britain made India great. Lots of bad things of course, but the country really got richer and richer
Then the decolonization happened
The system that the Brits placed require that the chosen leaders have a concept of Christian values and prioritize results over tribalistic ideals
Brits succeeded in making India great but their culture and belief system were completely tribal, clan-based, and hierarchy-strict.
Thus, the efficient system that was supposed to keep India running became an efficient system at creating a dysfunctional nation.
It's like having a nice car but replacing its engine with something not designed for it.
Society must work for its future. If they didn't figure out what things work and what doesn't, under their own merit, culture will not improve.
Thus, India doomed itself.
One way out would be to turn them Christians or at least learn to follow the Christian ways like Japan did
