Why is that an issue? If they are the founder of the company I think they deserve it, and if not, there must be some logical reason why they pay that person so much...
I think they're saying it's an issue specifically in reference to how employee wages have grown in comparison. If we look at previous decades, you'll see that CEO and other executive level pay has increased substantially, and has absolutely left employee pay in the dust. That isn't to say people shouldn't be paid more for a good or important job, but we should probably be keeping a watch to ensure those with plenty don't take even more from those with little. And if those at the top are taking more, historically, than their fair share, then that needs brought in line.
I’d bet most people can get behind the idea that those in leadership positions or saddled with greater responsibility should be compensated more. The issue for me is the magnitude of that compensation.
If they are the founder, they are likely not a public company yet and can grant themselves stock at great rates. Most do-ers aren't CEOs, they are busy doing.
