I had the thought that the only way to really fight against large corporations and billionaires is to compete against them. Start your own business. Amazon relies on third-party sellers more than anything in their business. So start a business and sell your items there. Don’t have anything to sell? People are a creative bunch, make something. Find a local producer of something and make a partnership to sell on an independent web site.
Good shower thought but not really practical on its own.
Amazon will completely destroy a small business at every category except being a small business. Even if you could, Amazon still mandates that vendors have the lowest price on Amazon.
With that being said, I do like that many other companies are getting on board with the Amazon style. It is nice to have options at least.
