Yes capitalism isn't about serving anyone rich or poor, or managing anything least of all the economy. Its about free markets - each person looks after their own financial interests and tries to make money and the big picture manages itself without needing central planners.
Its funny how so many of the worlds problems are blamed on capitalism when in fact central planning is the root cause of most of it. Look no further than central banks to see the ultimate centrally planned monopoly control over value of all things in all countries. Hopefully crypto defeats this paradigm.
