So you cannot see or understand the system by looking at an individual. System that divides people into making rational individual decisions (called free market economy) without any real way to conspire co-operation is always going to result in something that is irrational for everyone as a whole. Everyone has to "defect" and for every person you convince against their self-interest to "co-operate" there will be 10 more "defecting". If you want best possible overall result you need entirely different system like centrally planned economy which for example walmart and amazon already uses.
If you attempt to fix the system instead changing it entirely you will just end up making it worse because of regulatory capture. The fault I described cannot be fixed because it would be contradictory to the very foundation, so instead of actually fixing anything it will make the system even more unfair and perverted.
