I''m under the impression that shareholders have been largely powerless to prevent the huge payouts to CEOs. I've read of a number of cases in which they tried to.
I'm not quite sure how the mechanism by which these get awarded works in practice (and would like to know), but I'm pretty sure the preferences of shareholders are only theoretically a big factor.
What has happened in America, and probably much of the rest of the world but I'm only familiar with America, is that shareholders have become stupid.
Once upon a time, stockholders were mostly business savvy professionals who studied companies and provided money to the ones that seemed like they were well run and would turn a profit, which would be returned to shareholders in the form of dividends. Of course, you could forego a future dividend income and just take an immediate gain by selling your stock at any time, and the business savvy people who owned stock would make that decision based on all sorts of very businessy factors.
Then along came the mutual fund. Having observed that stocks tended to make money on average, someone found a way to sell some sort of average stock. It was great. You could buy what the pros bought, and they usually made money, so you should, too. What could go wrong?
Well, what could go wrong is that people didn't realize why the stock market had been such a good investment. it was because it was, on average, tracking investments made by smart investors. As the mutual fund gained in popularity, that money became increasingly less intelligent. The investors were just blindly giving money to a fund manager. On the other hand, at least that fund manager was a business savvy sort of dude, so that helped.
Then came the growth of the 401(k) plan. Suddenly, everyone could get in on the game, and millions of people were blindly shoveling billions of dollars toward some very rich men, with absolutely no knowledge of where it was even going. All that mattered was that the statements showed increase in the share price, which was what mattered to those oh-so-savvy investors in cubicles and assembly lines across the land. Business, shmizness. Did my balance go up last month?
And what has that got to do with CEO pay? Well, the business savvy investors in days of yore knew that if you threw tons of money at a guy and gave him incredible control over how to spend it, he would find a way to spend it on himself, unless of course you watched him like a hawk. So, the shareholders hired a few hawks, called Boards of Directors, to make sure the CEO didn't steal or squander all the money. As the mutual funds and 401(k) "investors" became a much bigger share of the pie, CEOs figured out that no one was really watching over their shoulders. More and more of them became very influential over the BoDs, and they hired compensation committees to ensure who would set CEO salaries, and those same committees would determine a fair level of compensation for board members, who labored tirelessly at as many as three meetings per year. Surely that's worth a large sum of money, isn't it? Any objections? Raise your hands? Great.
Summary: The "little guys", like you and me, became a much bigger part of the investor class, but we really don't like to pay attention to what people do with our money. We just blindly keep shoveling in the hopes it turns out well. Knowing that no one is really watching, they take as much money as they can get away with taking.
Or, in other words, we have met the enemy, and they are us.
ETA: And what do I think we, as in the government who represent us, ought to do about it? In my opinion, nothing. Everything being done is being done right under your very noses, perfectly legally. As long as we have a progressive tax system, they will at least help fund the infrastructure necessary for the megacorporations to exist.
