It may not be rich like first world, but reaching Mexico level per capita income and a safety net for basic needs + education and basic healthcare is possible within 3 decades. Corruption is reducing, infrastructure is being built like China of 2000s (almost) and a connected world is a very different place from what was possible 20 years back.
These days people want luxurious life. Those days are simply gone where people would be satisfy wit basic needs + education. And with the advent of social media like facebook/instagram where people tends to show off a lot this will make the situation more worst.
Not perfect, but i am seing improvements as more government services are moving online.
One example is passport. Previously it took few months and you had to bribe multiple offices to get a passport faster. Now you get passport within a week. And the only physical link left is the police verification.
Vehicle registration, transfer etc also moved online recently and reduced the scope of bribe there.
Land registration and records are also in the process of moving online.
But on the other side, corruption at political level etc are not reducing .
India's corruption rank was 94 before Modi came, and is currently 85, which is the highest it has been since Modi came. It has reduced quite a bit I'd say.
