Sheepman,
Sorry if I misinterpreted your comment. I didn't understand what you were trying to say, about being high enough to bid. Thank you for clarifying.
As for Game level requirements. Getting to level 4 is very easy, as the requirements are set very low at that level. Only 3 High Tech Corps and the Space Corps have a level requirement above 4. It would be annoying if the Corporation in question is one of those few Corp types. However, this is likely necessary to prevent people using CEOs as an exploit, to gain Corps that they are unable to build due to their game level.
As for the salaries CEOs pay. If the salaries are too high, then you benefit in the form higher income tax revenue. If the wages are too low, then workers will leave that Corp as soon as other jobs are available. Build a new Corp and the Workers will leave their low paid CEO jobs.
I'm not sure what you are referring to with CEOs locking shares. As far as I know, there is no lock function on publicly traded Corps.
If a CEO decides to leave Simcounty, but does not deregister there CEO. Presidents have a couple of options. Either Nationalise the Corp. Or, wait for the players CEO to expire. Then the Corp will be placed under Gamemaster management. A new CEO will likely take over the Corp, and you can work with the Corps new owner to find a setup to your liking.
As for paying for a poor Corporation. The amount you pay to Nationalise a Corp, is based on it's value. Which is in turn based on the Corps profitability. If the Corp is poor, it will be very cheap. If the Corp is expensive, then it is a successful and highly profitable Corporation.
Even if there were an evict function. You would still need to pay compensation to the CEO, for disrupting his profitable Corporation. Just as CEOs have to pay compensation to Presidents when they leave a nation. Additionally, there is the problem of where to evict a CEO to. A Corp is based in a Country, that country is it's home, it has no other base nation to be evicted to.
