It's actually interesting to think about Amazon's platforms. Most often what they do, is take some part of a startup or small business, a part that is relatively safe[1], over the long term for that business, and often serves as a part of moat, and let people do it on their platform, and leaving that business with a much higher ratio of risky-tasks/stable-tasks. The end result is that businesses are becoming much more risky(over the long term), more hit-driven, and much more hollow(job and knowledge wise). And it doesn't seem like something good for the economy. [1]For example, printing a shirt(and owning that printing machine). Or installing servers. Or keeping in-touch with customers and branding.
