This video from Spain reminds me of Neal Stephenson’s 1992 sci-fi novel Snow Crash, which features the Raft, a vast agglomeration of flotsam inhabited by impoverished south and southeast Asian refugees drifting inexorably across the Pacific, headed for California:
“When [the Raft] gets to California, it will enter a new phase of its life cycle. It will shed much of its sprawling improvised bulk as a few hundred thousand Refus cut themselves loose and paddle to shore. The only Refus who make it that far are, by definition, the ones who were agile enough to make it out to the Raft in the first place, resourceful enough to survive the agonizingly slow passage through arctic waters, and tough enough not to get killed by any of the other Refus. Nice guys, all of them. Just the kind of people you’d like to have showing up on your private beach in groups of a few thousand.” [p. 272]
Libertarians view Snow Crash as a utopian novel.
