I was going to say that I'm sure they're not actors... then I remembered former Hollywood actor Reagan.
I'd imagine that even serious, career politicians, with no acting experience, get more than a little crestfallen when they see how they're just a cog in the machine instead of being the driver.
In fact, I'd go as far as to say that no-one can ever be the sole driver - however much they'd like.
I'd imagine that all of the power-mad dictators of the world get a little crazier when they realize this...
Life in a regular job is not possible to do alone. Were social animals and everything is interconnected. Figurehead, actor or President there's too many plates to spin on your own.
How's that old joke go?
If you want to make God laugh, tell him about your plans.
