They do have to be concerned about where the money is going to come from to pay their mortgages when severance runs out. They got laid off into an environment where layoffs at companies they might have worked at before are reducing headcount.
Not saying they shouldn't have saved for a rainy day. This is a scary time to be laid off.
$20 lunch. Must be nice. I don't spend that on myself --- ever. My target for lunch (if I don't pack it myself) is $5. That used to be pretty easy but getting harder these days.
Fairly sure that none of the FB employees are paid so low where they have to stop asking their spouses to go on a $20 lunch with friends.
