And also those who like to keep a good relationship to the officials they have to work with on a daily basis. I can't prove or test it, but I assume that this category contains the biggest amount of people AND money concerning bribery. "Doing favors" to each other is just a basic social activity, especially if the other person is one with the power to change your life to better or worse.
In the US and China, yes. Outright bribery is rare, but people with "connections" get special treatment.
However, the article is about India, a country where corruption is so rampant that there's an Association of Dead People, who can't afford the bribe to have themselves "reinstated" after they were reported dead.
"Hi, I'd like to report, my in-laws declared me to be deceased, and have stolen my house and land."
"Hmm, your name? OK, it seems you are dead."
"Yes, and my house has been stolen. I'd like to file a complaint."
"You can't."
"Why?"
"You are dead."
People spend decades trying to get back on the books. It would be hilarious if it wasn't true.
