I understand your view, and agree that transparency is good, but "the work required" is largely preventing and defending against lawsuits by plaintiff lawyers, and those lawsuits cannot possibly benefit the shareholders (because whether the suit is won, lost, or settled, the money all goes from one pocket to another, with a cut going to the lawyers).
This may sound rough, but I don’t care about shareholders. In fact I consider them my enemy, or at least my class-enemy. Whenever they make money off of the shares of the company I work for, I consider that exploitation, and I want them to stop doing that. I also want them to stop paying me in stocks, and I want my—and my fellow worker’s—pension funds to stop trading in stocks. My shareholders are my exploiters and my enemy and my pension fund should not be my exploiter nor my enemy.
But while we live in this system which forces stocks onto me, and I have no say in the matter, I want it as transparent as possible, and I don‘t care how much it costs my enemies.
