I feel sorry for them. No one should have to die like that, being executed by savages. But, being rich and stupid is not the free pass in the rest of the world that it is in the US.
Travel like this is a kind of status symbol. I know when I hear, "I love to travel" I'm about to be subjected to a long, boring, self-flattering spiel.
And the more exotic the travel style, the higher the status. Missionaries, please. This reminds me of a couple who take fabulous safaris and take it off their taxes on a phony charity as "education."
