I totally agree with this. I had to deal with a situation like this at one point in time, where my manager was dictatorial, unreasonable and extremely defensive and saw every suggestion as an attack on his authority and would immediately run upstairs to the upper management and write people up. When I saw that normal dialogue was not possible with this kind of person, I decided to start agreeing with him on everything and made sure he wouldn't perceive me as a threat anymore. It completely killed any chance for positive feedback on my part but it also protected me from his outbursts because I wasn't giving him a reason to see me as a threat to his authority anymore. Going to their bosses does nothing and more likely than not, you will be perceived as a moaner and troublemaker and may get yourself into even more trouble. They are holding those positions because the management TRUSTS THEM. They are also in charge of keeping their people in check.　Also, if the organization was any good, they wouldn't be putting people into these kinds of situations in the first place. Bide your time, look for work elsewhere (or wait until your project is over and get reassigned to a different team) and absolutely do not confront anybody unless you're prepared to walk right then and there if things go south (and they probably will). Shitty people/organizations don't change. Moving on is usually the correct course of action.
