We could overturn the Citizen's United ruling with new legislation that ends corporate personhood.
Doing so would not end capitalism, it would not make us socialism, it would bring about healthier business and healthier government.
Unfortunately, I don't believe there is any way to "fix" for-profit corporations because of their charter. The only option is to remove for-profit corporations as a business entity and only leave non-profit corporations. There shouldn't be a need for the protections a corporation offers if the company isn't doing anything illegal.
I believe what people really resent are the "chartered for greed" corporations. Everything they do is to maximize profit which warps even the things they do that "appear" to be from a good motivation. They try and make their company more appealing by donating to charity, claiming some more environmentally friendly product, or enhancing workplace benefits but that generally doesn't make things great for the employees in the long run. That drive for money taints everything the company does and makes it a "soul crushing" environment. No one, not even the CEO, really feels ownership of the company because the charter removes the possibility of "humanizing" the company's decisions.
The government is the only real protection from getting ground-up and spit-out by corporations. Also, as a previous post pointed out, if becomes very expensive to just ignore the problem of people that are unable to work for whatever reason. We would go broke trying to put everyone in prison that was forced to steal because they couldn't work and had no other source of income. No one is more dangerous than someone with nothing to lose. This is why capitalism vs socialism is a ridiculous argument. We need both of them.
Seriously!! Human beings have an incredible power-to-weight ratio, can convert a wide range of hydrocarbons to energy, can self-heal minor damage and you think the fact that air and food go down the same tube is a design flaw?
It's very easy to criticize something we don't really understand. Everyone who thinks humans could be better designed should do so or shut-up.
Marriage is the triumph of imagination over intelligence. Second marriage is the triumph of hope over experience.
