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.
you will never be able to outcompete the 1% because the only way to do that is to exploit workers more than they do. liberal propaganda may talk a lot about how growth without harm is possible, but it’s all just that, propaganda.
what I and a lot of anti-authoritarians propose is starting co-ops whose aim is to fight against competition, and to abolish the profit motive as much as possible. also organizing into neighborhood councils that function based on consensus democracy to autonomously govern the neighborhood against the wishes of oppressors like the state, the cops, landlords and the owning class.
the only way to escape late-stage capitalism is to go against this cancer cell ideology called infinite growth by adopting this thing called degrowth.
the Argentinian example is extremely inspiring for workplace self-management:
