Many shareholders get very upset at large corporations whose CEOs and board of directors hijack the company for their own personal gains.
Once in control the CEO or the chairman of the board would stack all their friends as board members, "yes people" they can trust, but also people they can trust to vote their way and vote their salaries and bonuses higher and higher.
They in turn would figure out a perfect metric where they could justify performance of the company that quarter by how much the company made or by how much the company saved, and the poor shareholders were stuck paying these high salaries, as the profits did not go back into the company.
To counteract this there have been endless lawsuits by minority shareholders, and many hostile groups that would take their plight to the media that is, hurting shareholders equity as well and their own pocketbook.
The SEC stepped in and decided that board members should contain people from outside the industry, perhaps academics, to break the strong chain of friends from hijacking companies.
Unfortunately, this caused a problem because many ignorant people were put on to these corporate boards, they did not understand capitalism.
They had a different sense of idealism that had nothing to do with profits.
A free-market corporation's job is to make money and increase shareholder wealth.
A person on the board of directors who is too idealistic and is not profit motivated is dangerous towards that goal.
Capitalism must retake the board rooms if corporations are to make money.
Please consider all this.
