I also think that 'ideas' are far more helpful than gimmicky and trendy consumer products, assuming we really want to help people. DIY and smaller scale industries are more sustainable also, because it is more local, and more diverse, and tends to distribute wealth more evenly, throughout society and around the globe. I'm putting this out there as a philosophical argument more than a political one. Economics and Engineering for the simpler lifestyles won't as likely make you rich, but it does tend to be alot more interesting, in my opinion.
