India is still holding remnants of feudalism since their independence, which can be seen in certain areas and way of thinking throughout India. India is also a far, far poorer country than USA, per capita especially, there’s no competition.

Poorer countries are easier to corrupt and India will find it very hard to dig itself out of the hole it’s in without outside interference and a lot of prosecutions.

But, corruption exists in (I would argue) every democratic country. They make up stats and skew them in their own favour in an attempt to hide it, but the people on the street aren’t blind to what is happening and are very much aware of the corruption regardless of any statistics.
