Many? Which countries do not suffer from corruption? This seems to be the human condition. As the old saying goes, “power corrupts…”. It’s not of question of “if” a country is corrupt, it is “how much”.
True but India does seem to be steeped in it. I once bribed someone in India accidentally and didn't realise what had happened till afterwards. That's how embedded it is in daily life. I can't imagine that happening anywhere else I've been and I've been a few places.
