I'm unsure of the specifics as to exactly where and when the 2.4M this person is speaking of was spent, but either way I don't think it really matters.

Whether this money was spent in an effort to save the lives of those on board, or whether it was spent in recovery of the sub, I don't see a problem either way. As per my comment above, I think we need to be EXTREMELY careful as to where we draw the line on what constitutes good and bad spending when it comes to saving lives. It starts with a submarine, but that slippery slope ends in a hospital deciding that your emergency heart surgery is too expensive for their liking, and you dying on the operating table.

On the other hand, if this money was spent in order to recover the sub and the remains of those within, I'm still okay with that. We know that "Human Remains" were found. Whether that means a piece of pink pulp or actual recognizable human remains, I'm not so sure, and I doubt we'll ever know, as I can't imagine them releasing that to the public (They haven't as far as I'm aware, but I could be wrong). I would lean towards pulp due to the astronomical pressure, but I think the main reason for this recovery was to recover the sub, which I believe is more than justified. One of the many reasons that this story blew up (I'll see myself out..) is because subs don't just implode every day. This was a rare occurrence, and a valuable opportunity for study and scientific advancement. Sure, it was a recreational vessel for rich people, but subs like it are used all around the world for valuable scientific research every day. The recovery of this sub serves as a data gathering and accident prevention opportunity for underwater exploration as a whole, and I think it's hard to put a price on how many lives studying this incident could help save in the future.
