I had this idea: What if we criminalize extrem riches. It would deter people from endlessly accumulating wealth, if there is a legal limit. It will affect only the 1%. It will not be just towards them, but it is necessary. I believe its not the people who are corrupt, it is the power they have and its incentivis that makes them corrupt. Also, anyone who is currently extremely rich 💯 gained these amounts of riches through some form of exploitation (humanitarian or environmental). If you define exploitation as voilence inflicted, it would be more justified as well. This tiny change might force capitalism into a different direction or change to something different all together.
