You do realize that Amazon doesn't pay as much taxes as those small businesses? Isn't that an impediment for those entrepreneurs to improve?
I want to point out though, that this could be addressed with policies/laws/regulations. I believe that while the current big players like Amazon and Alibaba may be bad news due to how they operate, small businesses also benefit from having a "town centre" or a meetpoint where they can showcase how their products/services can be better than everyone else. i.e Such a platform is needed by SME.
I am digressing from the topic of this thread (OP was asking specifically about Amazon, after all), but I am optimistic of a good/beneficial alternative to Amazon. Maybe I am too naive, but hey, that's just most of the people believing in blockchain and the ideals of cryptocurrency
You're saying that blockchain and cryptos are ideals to believe in? Well, let me correct you. Both blockchain and cryptos are financial tools for businesses and individuals to use and enrich themselves.
Therefore, whether one wants it or not, both are slowing making their way in the global economy. Their place in the world is no longer an ideal, but rather a reality.
