I'm very into graphic design, and interaction design, but the fact that it all goes to selling soap and deodorant and candy makes it feel like such an empty pursuit for me. How many of the people coming with these things could instead be putting their talents toward more artistic or meaningful ends?
Of course, ultimately I'm a capitalist, and marketing does provide a valuable service to a capitalist society, and there are myriad reasons the people doing this kind of work should be doing it. Sometimes, I take a step back though, and can't help but wonder if there's a better way. Ultimately, if I want to change things, it is incumbent on me to provide an alternative, and I just don't have one.
