While I agree with the sentiment, doesn't your own article state that immediately after the incident, multiple countries launched a group search and rescue mission which saved a lot of the victims?

The story about the millionaires, at least to me, is less about the fact that they're millionaires, and more about the fact that we have tourist visits to the remains of the Titanic. At this point I don't know who was on that tiny submersible but I'm intrigued with the tech and what could have gone wrong.
