You're right. Another issue is the age divide. Younger people: harder hit economically, less so by the virus; older people: harder hit by the virus, less so economically. This can only worsen the class fissure which had already developed along generational lines.

Sector, yes, but I'd think businesses in similar industries with similar cash on hand for their size would do similarly well, regardless of size. As ancestor said, it's a class divide, but it's by sector and cash-on-hand, not so much by size. E.g. J.C. Penney is big-ish, but struggling because of store closures and cash-on-hand.
