Been there done that, in some places being good at solving problems makes some people think you're attempting to damage them. That attitude is common among workers who aren't good at their job and have no intention to learn, so they see you as an obstacle rather than an opportunity to ask questions. In sane working environments, should some of them get at war with you that wouldn't be a problem since you're better and if a choice among one of you must be taken the result would be obvious, but I've found and experienced on my own butt that when someone reaches a technical position without having the necessary knowledge it usually means he or she is much more socially skilled than you, or has very strong connections with people who take decisions, both aspects making that "enemy" impossible to beat. When you smell a situation like that, just leave asap: any attempt at fighting the war will consume you from within without giving anything in return, except maybe a better knowledge on how to avoid that in the future. Not sure if it's worth the pain, though: in one really bad situation I've experienced somatized hemorroids for nearly one month before I finally decided to quit, and two days after taking that decision they were completely gone and never returned.

Then in some other rather corrupt places, money is made by dragging the solution ad infinitum or close to it, because penalties for missed releases are crafted in a way that makes delays still more profitable than finishing in time (easier when supplier and customer are "in the same bed" and money comes from the government), so that if you offer a quick solution you immediately see people looking at you like you were a bank robber. Oh the irony:)
