I used to have the same message at the beginning of my stories and my reach dove even lower as a result. It kinda went back up when I stopped writing these.
Good article, but I don't define capitalism like you do. Capitalism is the free production and exchange of goods and services aka creating value for other people, which necessarily leads to private ownership.
Activities like "investing" or speculating cannot be considered capitalists because they don't create any value, and should therefore be forbidden in a *real* capitalist system.
