Great article with interesting historical insight. Thanks for posting!
This part (and the slavery justification stuff) particularly stuck out to me:
> "If you're unacclimated, you basically languish in professional and social purgatory," says Olivarius, who is writing a book about how the disease shaped the city's social structure. "Bosses will not hire clerks and bookkeepers who are not expressly acclimated. Women will not marry men not described as acclimated. You can't live in certain neighborhoods, and people will not rent rooms unless you're acclimated. Certain social circles will exclude you. And so this creates this hierarchy where you have people who are actively seeking to get sick.
