Money.
They pay many people salaries that they’d have trouble getting elsewhere. If these people stick around for the dream even after the money dries up, then I’ll be impressed.
The sentiment I’ve heard so far is “let’s wait this out, and hope it goes back to business as usual.”
The ethical have likely left already. Those who are most talented and in it for the money will likely be next out, if things don’t turn around. Then they’re left with the untalented and overpaid, who will cling on for as long as possible while the ship sinks.
