Should corporations have to disclose more about their executive pay structure?
Well, if they are public corporations created and supported by state and federal laws then a case can be made that, yes, they should be very transparent. Problably more than Barney Frank proposes.
However, this simply points again to the failure of government created organizations. Every year there are more patchwork bills to regulate corporations and, it seems, we hear more and more about what is not right with them. Let’s solve the problem! Let’s end government protection of corporations and the concept of limited liability corporations. If you are going to play you need to be willing to assume the risk.
And, yes, I disagree with Doug at Below the Beltway who says:

A possible end to the inane idea that so-called “commercial speech” is less deserving of First Amendment protection ?

As noted here when a business is structured like a human then we can consider applying human rights.
