In the coming ressecion, will it be huge corporations or small businesses hit hardest?

Small business as always. They don’t have the financial buffer zone that large corporates have. Most big corporates have already called a halt to new hires and have trimmed back spending in preparation for the recession. Depending on their markets some big corporates will be impacted more than others.

Large tourism or travel companies will be hit hard as will retail companies including Amazon as regular workers curb their spending. Amazon already missed their financial guidance in the last quarter because of the reduced online spending.
Travel takes a hit because regular folks don’t fly anywhere during a recession.
