Bezos and Musk are also founders. The basic problem with CEOs is that they pose a huge agency issue: they are supposed to be appointed as agents of the owners who are themselves represented by the Board of Directors. However, no one has ever found a way to provide effective oversight to ensure that CEOs act in the interests of the owners rather than in their own interests.

Attempts to tie CEO interests to owner interests by tying compensation to the company's performance have thus far failed, mostly because a) the fraction of compensation isn't sufficient to overcome the CEOs self-serving motivation or b) the specific tying system can be gamed to the CEO's advantage.

Furthermore, there is an asymmetry in the degree of interest between the parties: CEOs have a very large interest in maximizing their own compensation, while shareholders see CEO compensation as one expense amongst many others, and as such are less interested in it.

These issues have been known for a long time, and again: no one has come up with a viable answer. Anything anyone who is posting here thinks of has almost certainly been thought of before, tried, and seen to fail.
