… yes. I think so. Why would I feel bad about that?

I would correlate the convenience of research about a very potentially deadly leisure expedition directly with wealth. That seems reasonable.

If this was a gratis expedition for underprivileged children, yes, I think that would have been worse.

I think the big point is that they had all the money in the world and couldn't be bothered to spend any of it on their own safety. On top of that is the fact that being a billionaire is deeply immoral.
