Like just last night, someone was asking why the hobby was getting more expensive and I was explaining that I thought it was because of the laws of supply and demand. The hobby is growing, more people are interested in salt water tanks because advances in the industry have made it easier to keep one. More people are buying tanks and equipment, which means demand is up. High demand, high cost.
Then some fool comes in and tries to start an arguement with me that there is actually no law that states companies have to raise prices because more people are buying a product.
