The Great Filter will be based on a simple question. Is a company run by entitled, out-of-touch, maladaptive executives? Or is a company run by strategic executives, who see which way the wind blows and adapt accordingly?
The loser companies will be run by execs who have only known a surplus of humans, always another available in an instant to take the place of some serf who doesn't run fast enough or jump high enough. They refuse to pay employees more because that's not how it works. They have always had all the power in the employer/employee dynamic. They will lose their best talent, the people who make the company work, who make it profitable. Eventually there won't be enough people to do the work, standards will slip, clients will be disappointed and leave. The company will be a sinking ship and the rats will jump off right to the end when the company is either gobbled up for their assets by a competitor or simply bankrupted.
Meanwhile, those companies that see the Covid caused deficit of humans realize what is going on. They see this crisis as an opportunity. They lure the best and the brightest from their competitors. They know that when you keep your people happy, your business will thrive.
The Great Filter will take time to complete, and some idiots will slip through the filter through dumb luck or a large asset base to survive on. Their pay will still be the worst in their industry, but they will have raised it enough to just barely keep people long enough to keep the business in motion.
