It does seem like this conversation pops up every year. Sometimes it can get nasty and sometimes it can be very constructive. This thread is one of the better ones.
That being said, my experience over the past 20 years in the viz biz has shown me that in order to survive, its not just about creating the perfect image/movie for the client, but also about building client relationships. I have found that if you are completely transparent throughout the process, listen to what it is they want, and deliver a successful product in the (always too short) amount of time they require, that they tend to see the value of the work and return to you for your services. You treat them as if you are all in this together and you become part of the team. My clients tend to be primarily Architects and Developers and the work is mostly medium to large commercial or multifamily residential. This pocket allows for me to charge a "normal" amount for my work due to the fact that my client is not the one directly paying for my services. The size of the project also helps in that what I charge does not look like much compared to the overall design service budget. Many of my clients already know what I charge and work that into their proposals so that there are no surprises right from the start. It is really up to us to define the value and to educate our base locally, because we can not change how it works globally. If someone asks you, "how do you compete with the companies charging $150?", the answer should be, "I don't".
This industry is not an easy one to crack, and it takes a lot of kissing hands and shaking babies and I wish you all luck. We all need to continue to support one another, no matter where we do our work.
