How so? As I said, the reasons you gave would apply to both. Most citizens are not educated in political science; they don't understand foreign policy, etc.

Should the janitorial staff have equal says as to the executives in how funds should be allocated? Do we recognize that not everyone has the same skill set and level of skill as others?

We don't vote for how the government allocates funds, though. We vote for representatives who do that for us. It could be much the same in corporations: you would get to vote for your bosses.
