If we had a justice system, that $10.8 billion would be recoverable, and used to try to rehabilitate the victims. But we don't have a justice system. We have a legal system, and a financial system.
When plunder becomes a way of life for a group of men in a society, over the course of time they create for themselves a legal system that authorizes it and a moral code that glorifies it. Frédéric Bastiat
The Bastiat quote is on point if your criticism of Purdue Pharma is that it profited from the medical licensing laws and drug prohibition laws that unfairly proscribes teenagers from buying madak cigarettes on the free market.
If the criticism is merely that they made money selling addictive drugs, this really isn't what the quote is about.
