Capitalism is an economic system, not an ethical one. It doesn’t cause inequality and abuse of workers. Unethical behaviour by some businessmen is to blame for that. Leave Free Market Capitalism alone: it has raised Billions out of poverty over the last 30 years. Capitalism is ethically neutral, but people are not.
Enforce the Laws against unethical behaviour: The Law is a system of ethics, so do not expect an economic system to regulate people’s ethical behaviour: that is a job for the Law, the police and the Courts are there for this.
