I was going to say something along this line. While 505 mil might sound a bit exorbitant to be fair chance are without his ideas, support, backing etc it wouldn't even be a company. Also if that is only 3% of the company value then I would imagine the other investors are beyond thrilled!
I would concur that say the guy or girl that comes in and gets hired to take over a big existing company should probably get significantly less then they currently do but many would argue that's the cost of having/acquiring a CEO.
People will use the same lines for star athletes but truth is their pay is such a small percentage of the wealth they help accumulate for their owners and leagues.. I've never been too upset about someone doing really well or getting obscene wealth from their careers.
It's what they do with it that I would prefer to hear about and then I'll make my decision if it's wasted or not.
