It's rapidly becoming a pet peeve of mine whenever someone calls an unexpectedly hard domain and the appropriately high-priced businesses that grew around servicing problems in that domain a "racket". It's just plain intellectual laziness.

My mom recently finished a framing seminar that cost her a lot of money to go to, invested a ton in equipment, and talked my ear off for two hours about why custom framing costs so much and why there's only a handful of framers in any area, and it gave me the impression that this isn't a market that's going to be disrupted any time soon.
