I've never had to endure any of those things because when they arose, I quit the job. And when they arose again in the next job, I quit employment, and contracted. And when (different) problems appeared with clients, I quit consulting forever and built a hugely revenue-positive product business where I am the reigning monarch and believe me, life is now very, very good.
Nobody can tell me what to do now except the govt and, outside taxes, they really don't give a crap.
If you want power, you have to make it for yourself -- build a business that generates money independent of clients or bosses. One to five big customers (bosses, clients) hold huge power over you -- a thousand small customers hold little power over you. You need to keep em happy, sure, but that's not so hard, because you get to pick your own customers, and you get to choose to keep them happy exactly how you want to. But if one of them's a jerk? Or five of them? Or 100? Tell them to fuck off.
The bottom line is that a person who wants to remain ignorant of the money-making side of business will never hold power. Employment is the opposite of freedom.
(PS — taking investment is just another kind of employment. A kind of debt, really, repaid with control instead of interest.)
