I'm not going to touch the Mariel comment, but I will address the linkage between the wealth and the idiocy.
It's one thing to be stupid because you don't have the knowledge. That kind of "idiocy" is understandable.
It's something quite different for a guy who inherited money and has spent a lifetime trying to be a thrill-seeker (wanted to be an astronaut, etc.) who has all the knowledge at his disposal and then rejects it, while subsituting his own dismissiveness and arrogance and rationales for cost-cutting and safety-shirking.
Here's the reality. In his pursuit to make "staring at the Titanic" affordable to the masses, he ended up costing a bunch of countries millions of taxpayer dollars for the week-long search for his dead body. There are valid reasons to have safety standards for such an endeavor, and it's not to "stifle innovation". You want to innovate a cheaper way to make a pizza, knock yourself out. But a "cheaper" way to go into the ocean 13,000 feet down and potentially involve dozens of ships in a nearly-impossible recovery mission?
Yeah, **** innovation. And **** "cheap trips to see the Titanic".
