Non vegans at least have the excuse of being deeply indoctrinated, and having 90+ percent of people reenforcing and defending their behaviour. The ultra rich dont.

In a way, they have been indoctrinated by capitalism, and are reinforcing that indoctrination by being the capitalists. I can totally believe that most rich people consider themselves "good people" because they have "succeeded" in the capitalist system.

Keeping people in a cage is crueler and riskier than just killing them.

That's debatable by itself. But I'm not talking about keeping people in a cage. I'm talking about trying to forcefully re-educate them and re-integrate them into the society. If they refuse or fail then that's on them. Even keeping someone in (a humane) prison for life is still less cruel then murdering them IMHO. This is demonstrated by the fact that most death row inmates fight their conviction up until the last moment, even though their living conditions there are awful. People who volunteer to be killed usually have severe mental issues, thus it's closer to suicide then an informed decision.

I don’t think you quite grasp just how far gone the rich are.

As I've said, I've met and talked with one of them. They're not all innately awful evil people (I don't think there are any people who are born evil), merely shaped to be such by their situation. And therefore, a lot of them could be turned into productive members of society with enough re-education, therapy, and honest work.
