What if you really like your job? What if you have invested years in building your product and want to keep working on it? What if you have lots of stock options that are vesting in the coming years?
There are lots of reasons why people would want to stay at a job.
Also, you are going to run into assholes in all walks of life. Learning to deal with them gives you options and puts you in control. If you lack that ability then your only option is to walk away.
In my case. Been trying to! Even with a good resume, if you have other constraints like geography, it can take a long time to find another position. Like, going on 6 months now. And with dependents, you need the income until you have another option. And, sure, I thought about quitting and pulling taps at the pub for a while, but that would make it likely harder to go back to my field of work. So, you suck it up, and navigate the quagmire of a dysfunctional workplace and spend your spare time networking and looking for other opportunities.

Yes some of us are lucky and work remote, have a large portfolio of nice enough clients, and not have to deal with corporate overlords. Let's be real though, this is a very small portion of the workforce.
Not to mention that if you go through the trouble of changing, which is bothersome for many practical reasons, you won't be able to tell if it is better or worse before you've been working for a while, which is a pretty discouraging for risk averse people.
His is truly the only way, if he owns the company he will soon lose business if more people do this and if he's middle management then his bosses will see where the problem is
