Ok, I'll argue.
But not in the way that was intended.
It's pretty evident throughout the TV series that the Krusty Krab is an exploitative capitalist business with an incredibly greedy and rich owner that openly flaunts his wealth, stinginess, and poor treatment of his employees. They're always busy, but the food is probably crap, because every time a new restaurant opens in town there's an episode about how the Krusty Krab is suddenly empty. But when the new place gets shut down through some sort of nefarious hijinks, everyone is flocking to get back to the Krusty Krab.
The Krusty Krab is China.
Then, in the SpongeBob SquarePants movie, we get the Krusty Krab 2; more or less the same thing, with a giant fancy logo, and insanely inflated prices, that (per the founder) exists solely to make money.
There's the US.
The rest of the world is probably best represented by a restaurant not in a city called "Bikini Bottom".
