There were specific points that Adam made to support his claim of corporate, fascism/socialism being mistaken for capitalism... I respect your position, but I'd take more seriously if you addressed those points, instead of just saying, "there IS NO SOCIALISM / COMMUNISM in the USA! PERIOD".
And honestly, you're right when you say that platforms such as STEEM are built on capitalism. You have the opportunity on Steem to earn based on what you put into it. In other words, the value that you place on your own self-ownership, creativity and ingenuity is a determining factor in what you are willing to earn.
