There is obviously merit to the traditional supply-demand argument that you just learned in school, but in reality, the ability to sell one's craft at the highest possible price has little to do with supply-demand, but the ability to sell.
I see that you are also a psychologist!
I see nothing in anyones posts here to be indicative of any kind of insecurities nor psychosis. Some lack a certain degree of maturity, but in most of those cases, its all in jest.
