Everyone answers to someone. No one person can make a change for an entire company to act ethically... In fact, government regulations are almost set up to force large corporations to act in whatever way brings them the most profit. If they are allowed to take unfair business with the government, they will. Corporations in general act in their own best interests, but so long as there is competition in capitalism, that's usually a good thing for the consumer.
I don't believe in corporate person-hood either, but neither did the founding fathers. Corporate person-hood used to be something you had to get special permission to do, it was only for a short period of time, and it had to be ruled in the best interest of the people (e.g. for building roadways.)
So i'm a capitalist, but i don't believe in corporatism.
If a company and the individuals can be held accountable, they will do what is their own best interests, which is to be responsible, and profitable. As a general rule, they work predictably within the system.
It was the government that changed. It was the government that started allowing for companies to be granted corporate person-hood on a whim. It's the government that illegally does business with corporations and creates a similar effect to a monopoly in the health and education departments. It's the government that bails out corporations. It's the government that is taxing heavily directly, and through the inflation of our currency which causes jobs to move elsewhere (causing your unemployment.)
The businesses are the predictable ones. Blaming them, and being a nuisance to the businessmen (whom you should really want to be on your side) is not going to solve an issue that is caused by a runaway bureaucracy acting outside of it's constitutional abilities with a massively bloated and seemingly "infinite" "budget."
Instead of asking why all the money from bailouts went to corporate executives, maybe we should be asking why they had the luxury of excess money that was taken from my, and everyone else's paycheck.
