Imagine going on a cruise to escape politics but the only reason anyone is on the cruise is to also escape politics so you're surrounded by a bunch of Jeff Tiedrich mega fans for 4 years with no escape
I heap a lot of contempt on people who completely miss the point of Starship Troopers, but that's nothing compared to the people whose take away from WALL-E is to dream of boarding The Axiom...
So cruises, a microcosm of environmental destruction and consumerist excess, are offering an opportunity to escape the results of continued consumerism and environmental destruction
Imagine going on this and coming back to find out that like Israel's been nuked and egypt has reformed itself into the neo-ayyubid sultanate somehow in the time you were gone
Let alone a 4-year cruise. Like, I have a feeling that the conditions on board may enthropy, due to capitalist mismanagement, to the point the cruise stay seems more like a nightmare... then again, no one's stopped falling for buying Tesla cars
It'll wind up as that flying party from Hitchhiker's Guide to the Galaxy, where it terrorizes the outside world by occasionally stopping for wine and cheese raids
Where a new bird flu has ravaged humanity, the last vestige of civilized humanity is a bunch of brunch liberals who took a cruise at an extraordinarily lucky time. How long till their cruise ship politics turns fascist?
The good thing, though, is if disaster strikes the ship and the wine cave libs end up in a Gilligan's Island situation, they'll be dead in a couple weeks because none of them have any skills besides being professional managers. They're just gonna delegate foraging food to other people and establishing a pecking order (with surviving crew at the bottom, obviously) until they just get thrown into the ocean.
Or we could get a Triangle of Sadness scenario where the crew takes over by being the only ones with survival skills, and bullies the rich libs into submission
if they get stuck on an island they would immediately start sabotaging each other and in the spirit of civility start voting people off the island just like those badass shows on their television
