Well, I mean, that seems economically accurate.
Alola is an island. Islands only have a limited number of resources, meaning a lot of it would have to be imported. It's why things in New Zealand are so expensive, it's why Hawaii is such an expensive place, and why Japan is also really expensive. Everything they can't grow has to be imported from places, and that takes labor and money.
Also, PokeDollars or whatever they're called are so worthless compared to the euro or dollar, a lot like Yen. Though, tbh, PokeDollars seem more like the Korean Won rather than Yen, since the conversion rate to a dollar is so insane. Yen are worth about a cent, give or take.
Anyway, POSTED!
