"First, the board who decides the CEO pay are not objective. They are friends with the CEO. They are not objective."
Well you might be right, but aren't hostile takeovers, activist shareholders, etc. disproof of that? In fact, the article mentions that it was activist investors who had Marissa Mayer instated, though I don't really know the history of Yahoo that well.
"Executve pay has been on an insane runaway explosion for years. You can say "That's because the companies are so successful!" But Yahoo is evidence success has nothing to do with it."
It's pretty weak evidence, considering that Yahoo was very succesful for its shareholders. I mean it's one thing to make the argument when the company fails, which I still don't buy. But to make the argument when a company succeeds, by claiming it didn't succeed enough, or that the CEO wasn't enough responsible for the success?! (Defining success as what shareholders care about in this case, which is making money). We can see examples of CEOs who do much worse and destroy lots of value. And I'm not even talking about the fact that they had to pay Marissa Mayer enough to take the risk, or that you can't judge investments solely on whether they succeed or not, since all investments are risks.
But I'm still left with one thing I simply don't understand here - who are you trying to protect that is getting hurt? The shareholders? How are you protecting them by limiting the ways in which they can use their money? If you really think that shareholders aren't well represented and therefore make bad decisions, then maybe you're right, but wouldn't the solution be to fix that problem, instead of attacking a symptom?
"And I would argue even if it were due to success; the workers should be benefit at least as much as executives, and they don't."
Not sure what you mean by "at least as much", but workers do benefit. They tend to hold shares of the company, which have increased in value just as much as the CEO's shares. Salaries in e.g. tech companies are much higher, which is another way in which workers benefit.
