Change is feared, change is risky, change can sink the boat that floats. The question is why change a formula that works? Well it is all down to opinion and what one's opinion is of the current state and how this fits in with their own beliefs.
When one's beliefs are threatened then this provokes a defensive reaction. If a person is true to their beliefs in whatever shape or form then they will stay true to those beliefs until the end (whatever the end is).
Design is a wondrous subject filled with many cynics and many contradictions. Feeding and succumbing to this supply and demand attitude the western world has created rather than believe and achieve. In today's society we consume products rather than create products. Consuming is made easy by large corporations who have an infinite back catalogue of wealth and as the Average Joe inspires to be a person of wealth, we consume this product in a benign desperation that this product will bring us that fame and fortune we desire.
Design is partially to blame for this. In a lifestyle where aesthetics are dominant in both the product and in human qualities, we supply beautiful products for the beautiful people.
These beautiful people with their beautiful products are normally skin deep shallow and desperate human beings who do not live life but trample on those who do and consume the consumers to achieve the life they so long for.
Our demand for certain styles at cheap prices both cripples the integrity of the design industry and the designer. Designers are primarily people pleasers and pleasing is easy to do as we know what works, what people will buy and then repeat the process... Ikea for example do this and we as consumerists love Ikea. Ikea is to the design world what Boots is to the pharmaceutical industry, It is a cliché almost cop-out industry that relies on supply and demand, and we consume it (as do I).
The point that I am trying to make is that consumerism is everywhere and no matter how hard you fight it or don't believe in it, you cannot avoid it. It creeps in unknowingly like a cancerous cell eating away at the core of what makes us human beings... I included ashamingly.
