Are you saying Amazon isn't a positive? Or that Bezos didn't contribute to making Amazon what it is?
I think it's pretty clear Amazon is quite a positive given by how many people like using it so much for it's convenient 1-stop shop, quick shipping, and hassle-free return process.
Are you saying it would be better to have to shop at 1000 different little websites with probably crappy or at least inconsistent return processes?
People would be more likely to shop in their local stores, buy local products, and sustain the local economy.
