I feel that's the case in many professions like plumber or car repair that people are reluctant or unable to DYI, whose services aren't going to be needed often, but that are accompanied by acute pain when they're needed. That tends to make people cost insensitive because they need pain relief, they have few points of comparison, and don't anticipate needing the same service again soon.

Sorry to say, but I'm not sure the IP law profession is different... I probably have worked with about a dozen attorneys hired by my employer to file patents on my behalf, and there were two lawyers that stood out a lot. They understood the inventions, what we claimed to set them apart from prior art, and produced filings that were relatively brief and to the point. The rest of them didn't really get the stuff, sent us draft filings that made me cringe because they were shallow copy-paste jobs, etc. If you're one of the better lawyers out there, I hope your clients are rewarding you appropriately for it!
