We can elect legislators who are opposed to abuses like Guantanamo Bay and campaign on fixing it.
What can we or the private sector do about abuses in the private sector?
The private sector is not above the law. The problem is that the government is. This is why, while both can misbehave, I see governments as a much, much larger danger to the average citizen than corporations. And the history agrees with me.
>market misbehaving is punished by the market through the consumer.
Can you explain how the consumer punishes private sector entities engaged in human trafficking, for example? It seems there's plenty of evidence that deception and cutting corners is the most market competitive behavior that corporations can employ which allows them to offer the most appealing prices. Therefore market misbehavior is rewarded, not punished by consumers because the price signal is too reductionist to capture all of that.
>And the history agrees with me.
That is debate-able
