I don't think this is anything to do with capitalism per se, this is the weak being exploited by the strong. Big fish eats little fish. This is the way life works. Capitalism works within the same context but is not the context.
It has everything to do with capitalism because it systemically enables this sort of exploitation. People act based on the systemic pressures they're exposed to.
I don't think it does enable this sort of exploitation. I think the exploitation cannot be avoided, in either capitalist or any other society, including communist.
People act based on the systemic pressures they're exposed to.
I think there is no system that can avoid the basic functions of biological life which includes the strong praying on the weak. Big fish eats little fish. This is life, regardless of what system evolves on top of it.
