"This brings a whole slew of other laws into effect and you will likely not find a corporation that is declared a criminal gang or criminal organization."
This was precisely my point. A very large chunk of corporations have behaved like criminal gangs and are not treated as such. It may well be the correct application of the law, but it is again a classic example of one law for corporations and another for everyone else. HSBC have recently behaved like a criminal gang. They should be declared and treated like a criminal gang. If a small business owner had done what HSBC has done they would find themselves behind bars. If you would like to test your theory go set up an accountancy, have 90% of your customers be legit and 10% Mexican drug lords. I look forward to your treaties on how all business are treated the same from the wrong side of a jail cell.
"Firing someone, negotiating their contracts and so on is not an unethical act."
It is if you own the legal system. If corporations have to accept state representatives in court, if all donations to politicians are outlawed and our tax system is reformed so that providing a job is not artificially restricted then we can talk about agreements between employers and employee as though they were free agreements. You cant buy the legal system, buy the legislature and artificially inflate the price of labour to ensure employers have monopsony power then call the resulting labour market 'free'.
