You read it. Having everyone set themselves to CEO difficulty actually creates a different game, it's so much more interesting.
After having tried it, it's hard to go back to manager, so much more dynamic, and every debt you take is just that much harsher.
Debt penalty increased from 3x (Manager) to 7x. 40-60% (?) less resource gains. 50% increased cost for buildings (steel type material only? not sure...)
It's great fun, and very harsh!
