There are a lot of good points made on all sides in this thread.
Here's my take on it: Whatever you do for a living, is it possible someone would do the same thing for less? Maybe you have something that you do that adds some intangible value to your trade. Maybe you simply make the customer feel warmer and fuzzier with your interaction. Maybe your boss just doesn't feel like headhunting for someone better because you're "good enough".
However, is it possible you are being overcompensated comparatively? Could what you do be done cheaper, or more to the point, could you do what you do for less money and survive? Of course you could. We could pay a family doctor $30,000 a year. For arguement's sake we'll say a rich uncle paid his or her tuition. Now their office would be small, the tongue depressors may be used a few times before thrown away, but for $30k a learned man or woman could tell you to say "ah", check your pulse, and tell you if they think an antibiotic would cure your ills. They are not performing surgery or using expensive machines. They are simply using their knowledge to diagnose illness. Anyone know any family doctors who make $30,000 a year?
Now I realize that's not a perfect analogy. I know medical insurance plays a big role as well as the protective insurance physicians must keep is a hefty price. However, does anyone think that anyone with that much prestigious societal value would settle for $30,000 a year?
My point is that some sort of market sets a price. I can tell you that in what I do the material cost is way under the price I command. Why? Well, it's a high overhead business with lots of moving parts, its seasonal and weather dependent, and any construction contractor had better hold a multimillion dollar insurance policy for protection. Also, I'm worth it. What we offer, how we do it, the quality, the legacy, etc. The market determines that is worth a premium. There are guys who do what I do for less, and they have been doing it for a couple years, maybe. Our business has been cultivated and adjusted through ups and downs over 65 years. For a budget buyer, that may not be worth a thing. For others, buy once cry once is their motto, and they want a known high quality.
I have my line in to the sand when it comes to what I will pay. Generally, $300 is my cutoff, but I usually dont spend over $200 for a splurge of a knife. I do plan on buying a Sebbie for over $450, but that's for a special achievement. As long as the knife pricing doesn't outpace my earning power/disposable income, I will pay the price. The market will determine when it's too high to bear and will adjust.
IMHO, there are many, many more industries where we as consumers are being fleeced on actual necessity items. I save my ire for them over my hobby.
