RE: "I'm particularly concerned by their abillity to often "settle" criminal charges with a fine and no admission of wrong-doing."
This is a result of plea bargaining and individuals can do that if they can afford a good lawyer and have a good case. An example is in the United States, an individual could please no contest to a charge and pay a fine. It is more or less the same thing.
I am not sure if companies admitting guilt would really change anything. The main reason is no one cares if a company pleads guilty and the other reason is prosecutors can compel guilty pleas through plea bargains (i.e. either you plead guilty, or we will go to trial and ask for a very harsh sentence).
That seems... I'm not sure what, but we do limit what convicted monopolist corporations are allowed to do. It's not the same thing as physical jail, but just because we can't physically put it in jail doesn't mean we shouldn't find it liable for malfeasance and hold it accountable and extract reparations from it.
Let's say a human being--a flesh and blood one, not a corporation--is convicted of negligent homicide and is sentenced to 4 years in prison. 100% of that person's income is lost for 4 years. For the rest of their life, after they're out of prison, their income potential is drastically reduced.
If that's what our judicial system is, then let's do that to corporations, too. Try the person--the corporate kind, not (necessarily) the flesh and blood kind--in criminal court. If the person is convicted of a crime, sentence them as per the sentencing guidelines. If the sentence is 4 years, then take the revenue of the person over the previous 4 years. That's what the fine is.
Easy peasy lemon squeezy.
Yes, and if a company breaks a law, there was at least one person at the company who also broke the law. When the mob breaks laws, we use RICO. There appears to be no equivalent for corporations.
