If my CEO is going to demand internal pre-prepared solutions to everything, then I'd demand that they be competent enough to not need my input anymore.

I mean, "hire someone who knows how to fix this" is obvious enough that it needn't be stated, nor defended behind this "bring an idea for a solution, don't just bring a problem" talk.

Which frankly sounds like something a motivational poster writer should be saying, not someone concerned with running a business. Platitudes are rarely the solution to a meaningful problem, in my experience.
