A corporation exists for one purpose — profit. The responsibilities, the concerns and the goals of government are very different from those of corporations. Government cares about its neighbors and allies, making security and world peace a top priority and spending a large percentage of the federal budget on national security and international relations.
Corporations care about no one but their shareholders and do not have friends. Effective government has compassion for its elderly, poor children and the disabled, and provides a safety net program for its citizens in distress (as in the case of weather disasters, terrorist attack or devastating illness). Corporations do not know (or need to know) the meaning of compassion.
Government provides police, fire, highways, parks and education for its people, while also providing good working-class jobs for teachers, cops, firefighters, engineers, librarians, etc. Corporations provide jobs, but will ship them overseas for higher profit; will fight to keep democracy (unions) out of their workplace and will pay their CEOs outrageous salaries and bonuses while using every loophole that Congress gives them to avoid paying their fair share.
Unfortunately, the far-right Supreme Court has allowed corporations to buy our government through their ruling on Citizens United. Mitt Romney, with the help of his friends, Karl Rove (Crossroads GPS), the Koch Brothers (Big Oil), the coal industry, the U.S. Chamber of Commerce, foreign banks, and corporations and billionaires, is benefiting from the lack of public oversight of our elections and from the obscene amounts of private money flowing into Republican campaigns. Unions were once able to stand up for the working class and against the corporate contributions, but Republican union-busting tactics have diminished American unions to a fraction of what they were just a few years ago. They can no longer even begin to compete with the vast amounts of money pouring into the Republican campaigns from corporate giants.
There are profound differences between government and corporations. Don’t let the far right deceive you. Unless you are a billionaire, they are not on your side. And just because you’re an outrageously wealthy businessman, doesn’t mean you are qualified to be president.
