Regular folk = the average person who does not belong to the sub-group affected by the anomaly.
Example:
"Amex accounts are getting shut down with no explanation."
"What? Where did you hear this?"
"Well, a lot of guys on DDF are reporting closures."
"Oh, those are DDFers. What about regular folk?"
Here, employees of the meat-packing plant are experiencing an anomaly: a high rate of infection and deaths from Covid-19. It begs the question: What about the rest of the people?
Could have been worded better, but not racism or classism or any other kind of discrimination.
